But dates vary between sources and factors such as handle design can slightly change the date of manufacture.

However, I have spent many hours creating this identification guide and I hope you find it useful and informative.

Selden & Griswold cast iron 1873-1884

Matthew Griswold and two brothers from the Selden teamed up and started to make door hinges in 1868. Their factory was known as the “Butt Factory,” named after the type of door hinge (butt hinge) manufactured in the ironworks.

Selden & Griswold started to manufacture hollowware from 1973. But most of the cookware with this logo was probably made in the 1880s. Even though Mathew Griswold bought out the company in 1884, he still used the Selden Griswold logos.

After all, it would have taken a lot time and money to register new patents and to make new molds. Check out our other article to learn about the history of Griswold Manufacturing. Wikipedia also some information on Griswold. Although I hope my article is a little more detailed.

Erie cast iron (approximation date 1880-1907)

Erie cast iron is some of the most sought after vintage cast iron you can collect. Griswold used this logo between 1880-1907.

Erie cast iron
Erie cast iron was manufactured between 1880-1907. Over the years Griswold made slight changes to the Erie line such as the handle, Erie logo and the pattern number in the center. In total there are six known series of Erie skillets.

Erie cast iron skillets are very thin and light. Because of this they are more prone to warping. So if you are buying an Erie online, make sure you ask the seller if the skillet rocks or spins. That being said, I wouldn’t look past an Erie skillet just because it has a little movement.

Erie skillets are also known to be super smooth and are often priced similar to other vintage pans.

Other foundries during time, used Erie skillets as a template to make to their own molds. It’s not uncommon the find Sidney Hollow Ware and Wapak skillets with an Erie ghost mark. 

If you have an Erie skillet, you can further break the Erie logo into 6 different versions of the pan. The Wagner and Griswold Society has an article on the different Erie series.

Close up photo of the Erie logo. Erie logos were used on cast iron skillets made by Griswold Manufacturing Company.
Erie cast iron skillets are super light and smooth. However, if the skillet was used on coal or wood ranges it may have pitting on the base. It is not uncommon for an Erie skillet to have pitting.

Diamond logo

If you look on the back of you cast iron griddle and you see a diamond logo then it’s your lucky day. The Griswold Diamond logo is an early logo and it’s more scarce than other logos.

Griswold Griddle with Diamond logo
This isn’t a skillet but I though including this logo could be useful. It’s called the Dimond logo and you’ll likely see it on Griswold griddles.

Griswold manufactured griddles with this logo Circa 1884-1910. The logo is positioned in the center. Unfortunately, this is an area on cast iron often damaged by sulphur pitting.

Griswold Erie Diamond Logo often found on griddles rather than skillets circa 1884-1910

Griswold’s Erie Trademark

Griswold used this logo somewhere between 1905-1909. There are conflicting dates so I used the wider conservative timeline. Since Griswold used the Griswold’s Erie logo for a short time it is harder to find skillets using this logo.

The Griswold’s Erie logo is the first Griswold logo. It transitions from previously used Erie logos to Griswold logos. However, the Griswold’s Erie logo shares similarities which Erie skillets.


Look for Griswolds’s Erie skillets between sizes 6-9 and 11 to 12.

Griswold’s Erie logo circa 1905-1909. Great logo and is a little harder to find.

Griswold Slant logo with heat ring no EPU

The first of the famous Griswold skillet logos. The Griswold Manufacturing company used the Slant trademark from 1906-1916. Again this is a wide conservative range.

Griswold Slant Logo without EPU. You can see this is missing the words Erie PA., U.S.A under the logo.

The Griswold slant logo is easily with the word Griswold which is in italics. Also the Slant logo has characteristics which differ from Erie and Griswold’s Erie skillets.

Changes Griswold made on their Slant logo skillets

  • The size number on the base of the skillet moved from 6 o’clock to 12 o’clock. 
  • Erie placed below the Griswold logo. From 1880-1907 the word Erie was place at 12 o’clock. 
  • The patten number moved from the center of the skillet to 6 o’clock on skillet to make room for the Griswold circle cross logo.
Griswold cast iron "Erie" and Erie markings
Does your slant logo pre-E.P.U. have “ERIE” in quotation marks or ERIE without quotation marks? If you know why Griswold did this please let me know in the comments.

Griswold Slant logo sizes

Slant logo sizes range from 1-14. The largest skillet with the Griswold Slant logo is #14. A Griswold #13 slant logo can cost thousands of dollars to the serious collector. Needless to say, the skillet has to be in great condition for this price.

Griswold cast iron skillet No9.
Griswold slant logo skillets without EPU mostly do not have a number on the handle.

Griswold slant logo with E.P.U and heat ring

The Griswold slant trademark changed to add the words cast iron skillet in an arc at 12 o’clock on the skillet. The EPU is in reference to the words Erie PA., U.S.A., added to the skillet. 

The slant logo, however, remained the same. Again I cannot pinpoint the exact date of manufacture of the Griswold slant logo with EPU. If you have a Griswold slant logo with EPU the manufacture date is around 1909-1929.

Slant logo without Erie marking

I have only seen this trademark used on a few Griswold cast iron skillets. It seems to be quite rare. The logo is the same as Slant logo without EPU however this logo also omits the marking Erie.

Griswold skillet with slant logo no Erie
Here’s a Griswold skillet which is a little different. It lacks the Erie marking under the circle cross logo.

Griswold cast iron skillets without Erie marking had a manufacture date around 1909-1920.

Sizes available: I have only seen the large slant logo without Erie on size #9 skillets. I don’t know of other sizes with this logo.

Griswold cast iron skillet missing the Erie under the logo.
If you think this sometimes missing you’re spot on. The Erie is missing underneath the logo. Circa 1909-1926.

Large block logo

One of the more popular markings or trademarks is know as the Griswold block logo. The block logo is very similar the slant logo however, Griswold is no longer in italics. Griswold is in straight block letters. 

Skillets with the block logo probably were made between 1920-1930.

Griswold also made a wide of sizes ranging from 0-14, however Griswold Manufacturing also made a larger number 20. The Griswold #20 is a huge skillet and can cost a pretty penny online. 

The Griswold no20 is huge. The skillet is called the “Griswold Hotel skillet”.

Griswold cast iron skillet with Large block logo
The Large Block Logo was made circa 1924-1940.

Large block logo without heat ring (smooth bottom)

Griswold also made the large block cast iron skillet with a smooth bottom rather than the familiar heat ring. However, the sizes were more limited. Look out for sizes between 2-10 if you want to collect a full set.

Smooth bottom skillet are not as desirable to collectors as skillets with heats rings so you can expect to pay less for a Griswold without a heat ring. 

Why the change? Cookware with heat rings were for use on wood or coal ranges. However, with the introduction electric cookers, cast iron cookware with heat rings slowly gave way to cast iron skillets without heat rings. 

So if you want a great old skillet without the price tag of highly collectable pieces then a skillet  Griswold Large block trademark could be a great option.

Griswold made skillets with the large block logo and a flat bottom between 1930-1939.

Griswold slant logo without heat ring

Griswold also used slant logo on smooth bottom pans. Smooth bottom pans are like what we use today.

However, slant logos on skillets without a heat ring is not as common as skillets with a heat ring. These pieces seem to sell at a similar price to a smooth bottom Griswold with a block logo. 

Griswold made these skillets between 1939-1944

Cast iron skillet with Griswold logo
Here’s a smooth bottom pan with the large Griswold slant logo. Circa 1939-1944.

Small block logo.

The Griswold Small Block trademark is not as collectable to cast iron enthusiasts but they are still fantastic skillets. Griswold drastically reduced the size of the logo and skillets came without a heat ring. Skillets lost much of their character however, there are some beautiful skillets around with the small block logo.

Watch out for sellers pricing these skillets at high prices. You can expect to pick up a skillet with the Griswold small block logo at lower price than more collectable skillets. 

Not the say small block skillets are not any good. Rather the small block logo is simply not as collectible, so you may pick a good skillet at bargain prices. 

The Small Block logo were made between 1939-1957.

Griswold Manufacturing’s big brands were Erie and Griswold. But they also made cast iron cookware under different brands.

Griswold like many other foundries such as: Wapak, Wagner and Favorite cast iron made a lower grade range of cast iron cookware which was more budget friendly.

Table: Griswold Manufacturing’s budget friendly line


Circa 1880s to the 1930s

Iron Mountain

Circa 1930s-1940s

Victor cast iron

Victor was Griswold’s budget-friendly grade of cast iron. Griswold made Victor skillets between the 1880s to the 1930s. The Victor logo also changed over the 50 years. Simply marked in the beginning with Victor at the 12 o’clock position like Erie skillets. Later Victor cast iron skillets became embellished. 

Griswold Manufacturing marketed Victor cast iron as a lower grade however this does not mean lower quality. Victor skillets have super smooth cooking surfaces.

Close up photo of Victor cast iron logo made by Griswold.
Victor cast iron skillet were intact made by Griswold Manufacturing Co., Griswold made Victor skillets for around 50 years. Circa 1880s-1930s.

Iron Mountain 

Griswold made another lower-priced range of cast iron known as Iron Mountain. Unlike other cookware made by Griswold Manufacturing the Iron Mountain range doesn’t have any logos or trademarks which makes it hard to identify than other skillets. 

But there are a few characteristics which the Iron Mountain skillet series have which can identify them. Look for rectangular hole in the handle.

Griswold made Iron Mountain cast iron between 1930s-1940s. Since Iron Mountain cast iron was a budget range it’s probably not a surprise Iron Mountain skillets have a heat ring for use on older wood and coal ranges rather than new electric technology.

Here is an Iron Mountain skillet. Note the 4 digit pattern number and the unusual shaped handle.

Griswold Manufacturing made skillets for other companies 

Sears contracted with Griswold Manufacturing Company to make cast iron cookware for their department stores. The Cast Iron Collector also has some great information on cast iron store brands. Griswold store bands included:

  1. Hi Boonie,

    Happy Thanksgiving and hope you are staying safe! I really appreciate your thoroughness with this site as I have just gotten into cast iron skillets. Thank you for all the amazing details! I actually have a few questions. Do you know what the letter on a skillet (i.e. “704R”) represents? Does electrolysis affect quality? Also, are self-basting covers just as collectable?

    I sincerely appreciate all your insight! Thanks so much,


    • Hi Sam

      Thanks for getting in touch and kind wishes.

      The number on the bottom your skillet is a identification mark that was used by Griswold. Today collectors can use this marks to identify the size of a pan. In the case of your skillet a number 8. The letter following indicates the mold used to make your pan.

      Electrolysis is considered a safe and gentle way to remove seasoning from cast-iron. It is a method preferred by many collectors and those that restore cast-iron. There are some good videos on YouTube to learn how to safely set-up and use an electrolysis tank.

      Keep an eye open for those lids and covers. Some lids command healthy prices online for those needing a cover for their beloved Dutch ovens and roasters.

      Happy Festive season Sam


  2. I purchased items for an estate recently, and have found what I think is a super rare Griswold cooker, with a porcelain oven. It seems to be in good condition.

    • Hi Eric

      That’s a nice find. Griswold manufactured a wide variety of cookware including stoves and ovens. And you’re right, you’ll rarely see these ovens on the market. If you want to learn more about your Griswold oven. I recommend joining a few Facebook groups, and reach out to a collector that specializes in antique cast iron stoves.

      Thanks for sharing your find.

  3. Hi Boonie! I’m part of a FB group where a “debate” is going on about whether a Griswold Dutch Oven is a matched set with a lid. The lid is a #10 with a slant logo with EPU, and the oven is a large block with EPU, with the “Pat March 16 20” on it as well. The game changer? It’s NOS. Oven still has the label, the lid still has the tag. Story is it was in the attic of an older woman, to whom the Dutch oven was given to her mother. Do they match? Could it have been sold during the transition between the two logos?

    • Hi Ashley

      Thanks for the contact. A healthy debate is always a way to discuss different opinions and come up with new ideas and theories. It also makes collecting cast-iron fun as you learn something every day.

      Dutch ovens are tricky, unfortunately there is little information available, and an accurate timeline is hard to put together. Online information such as mine may inadvertently add to the confusion as the guide focuses on skillets rather than Dutch ovens. I hope to put together an article on Griswold Dutch ovens sometime in the future. But I’ll need to collaborate with a few collectors to piecemeal a rough guide.

      As for the debate, it’s an interesting one, probably by two knowledgeable collectors. At best, I could only add to the discussion. And I believe both opinions have merit.

      A Griswold oven with a slant logo and large block lid is not uncommon. And if I were a seller, I would have no problem labeling them as a set.

      However, I would make sure not to label them as a matching set. As the logos don’t match, and the owner might have purchased the lid at a later date. Although the original owner most likely purchased the complete oven with two different logos at the same time. It may be semantics, but I’d try to avoid any potential disappointment from a buyer.

      Cheers Ash, have a great weekend.

    • Hi Robert

      Well done on your find. Yes, it sounds like you have a relatively scarce pan. I believe Griswold made these collectable pieces circa 1930s-1940s.

      The Turks Head can be tricky to season, but they are great looking pans. I’d say you did well picking it up.

  4. I have a Griswold griddle. It measiures 24″ incliding handles, 22 without. On back it has #9, below that Cast Iron Griddle. Below the logo Erie,PA and further down 909 with an A under the numbers. Any idea on age or valur. I have no memory of where my husband or I where we got it from. Thanks

    • Hi Joan

      Thanks for sending in a question.

      Wow, you have a nice big griddle. And the 909 pattern number indicates you have a Griswold Long Griddle, with a small logo. Unfortunately, griddles don’t hold much monetary value compared to vintage skillets. But the sold listings on eBay should give you an idea on how much it’s worth.

      I believe Griswold made these griddles circa 1950s.

      Cheers Joan hope this helps.

  5. I have a griswold skilet but it does not match any of the pictures I see. It has the small griswold logo . Under the logo it has 7 inch skillet then under that the letter B. I am wondering how old

    • Hi there Mike

      Thanks for your question.

      It’s sounds like you have a Wagner skillet made in the circa 1960s. It’s a later version of Wagner Ware, but they are very nice pans. And I guess the cooking surface is very smooth.

      Happy Cooking

  6. Hi Boonie, I’m in search of a dutch oven and just today came across a ERIE (no quoatiion mark) 8 Bean pot kettle with side rings and matching lid. From what I can see it also possibly says PAT MAR. 10. 1891 in the center of the bottom. the Word ERIE is on the bottom outside rim with no other words. It also has a large 8 on the bottom. Cant tell if lid has number no photo of the underside of lid.

    Any idea on the age or value of this piece they are asking $40. If older then 1920’s I think that’s fair. Just wondering if you know about the age when it says PAT MAR. 10 1891 and what year of production that was made, since I didn’t see it in any of your photos above.


    • Hi Gary

      Thanks for your question.

      It sounds like you have your eye on an early Griswold Dutch oven or kettle. I think the price they are asking is fair. And I would be very happy with the purchase. Older kettles especially footed kettles are in less demand compared to Erie skillets because of how we cook today.

      But I would jump at the chance of buying this old oven/kettle, and when not in use it would make a wonder kitchen display. The lid is an added bonus. Hopefully the lid is flat to complete the old-time look.

      I suspect the oven was made circa-1980s-1900s. I don’t think it would be older than 1910. And a possible end of production date could be closer to 1905. As much as we look to the past, the those in the Victorian era were looking forward to the new century, and the date of the pervious century might have been perceived as outdated or fuddy-duddy. So I think it’s a late 19th to early 20th-century piece.

      Hope this points you in the right direction.

  7. I found a small Griswold pot with lid today at a flea market. It is 4” across and 2.75” high. Would you have any clue as to what it was used for or how much it would be worth?

    Thank you,

    • Hi Pam

      Thanks for your question.

      Griswold produce a number of smaller sized pans and Dutch Ovens. Some were toys, others were used to serve individual portions similar to how we use ramekins. Does your Griswold pot have any markings on the base to give us more information? I think your pot could be a patty bowl. And used to make individual pastry cases for savory dishes or desserts using Griswold patty molds.

      But any small cast iron pot with a pour spout and handle could be used for smelting metal. And I would urge caution if you want to use it for any food preparation as it could contain a few nasties.

      Hope this gives you an indication on how these small pots were used.
