Griswold Cast Iron Identification

Griswold made cast iron in Erie, Pennsylvania, and the pans have outlived the company by a long way. If one has arrived in your kitchen — inherited, from a junk shop, from an estate sale — there are usually two questions: what is it, and is it worth anything?

The first one is answerable, and this page answers it from a real source. The Wagner and Griswold Society — the collectors’ body for this iron — publishes a skillet chart compiled by R. G. Meadows, crediting Steve Stephens as its primary source for dates, that maps marking combinations to date ranges from about 1880 to 1957. Everything below comes from that chart and the society’s ERIE skillet reference. Every date on it is a circa, and we have kept it that way.

Read the underside in three steps

1. The logo. Is there a Griswold trademark at all? Early pans are marked ERIE only. Later ones carry the trademark in a slant, then in block letters, in changing sizes.

2. The pattern number. Pattern numbers start appearing on the third series of ERIE skillets from about 1892. A pan with no pattern number is either very early or not a Griswold.

3. The base. A raised heat ring around the outside, an inset ring, or a smooth bottom. The transition from heat ring to smooth bottom is one of the most useful dating clues on the chart.

The eras, from the society’s chart

The chart is more granular than this — it separates wood-handled variants and tracks which sizes were made in plated as well as bare iron — and if you are trying to pin down an unusual pan it is worth reading in full. We have linked it in the sources.

What the heat ring tells you

The raised ring around the outside of the base is not decoration: it existed to seat the pan over the hole in a wood-burning stove top. As kitchens moved to flat gas and electric surfaces the ring became a liability — it lifts the pan off a flat burner — and it disappeared. On the society’s chart, that transition shows up in the slant-trademark era: heat-ring pans to about 1916, smooth-bottom pans from then to about 1924.

This matters practically as well as historically. A heat-ring pan sits badly on a modern glass or induction hob, which we cover in cast iron on a glass top stove.

Pattern numbers are not inches

The number cast into the base or the handle is a foundry pattern number. It correlates loosely with size — bigger number, bigger pan — but it is not a measurement, and the same number can mean slightly different dimensions across eras. If you need the real size, measure across the top rim and, if you care about capacity for cooking, measure the flat area of the base too. That flat cooking surface is the number that decides how much food fits, and it is the figure most modern makers still refuse to publish.

VICTOR: the cheap Griswold

VICTOR was Griswold’s budget line, and the society’s chart dates the skillets to the 1940s and 1950s. They are the pans people are most often disappointed by when they discover the name is not the main trademark. For cooking, the disappointment is misplaced — it is the same iron from the same foundry. For collecting, it is real: a VICTOR is not a Griswold in the sense collectors mean.

What is it worth?

We are not going to invent a number. Prices for vintage iron move constantly and depend on the trademark era, the pattern number, the rarity of that size, whether the pan is a common No. 8 or something scarce, and above all condition — a crack or serious pitting takes a pan out of the market entirely.

What is reliably true is the shape of the market: common mid-century Griswolds in usable condition trade for a fraction of what rare early pieces do, and the gap between “a nice old pan to cook in” and “a collectible” is enormous. Our vintage buying guidecovers how to inspect a pan before you pay for it — the three faults that should stop you are a crack, a warp and deep pitting.

Should you cook in it?

Yes, assuming it is sound. An old pan is the same iron as a new one and it will not wear out; seasoning is polymerized oil bonded to the surface, and a pan from 1925 takes it exactly the same way a pan from last week does. If it arrived under a century of carbon, strip it back and start again — the routine is in how to restore cast iron, and surface rust comes off as described in how to remove rust from cast iron.

The one thing to check before you cook is flatness. Put it on a worktop and press an edge; if it rocks, the base has warped, and a warped pan on a flat modern hob heats badly and will never sit still.

If you would rather buy new

The honest reason most people chase old iron is the machined cooking surface — smooth pans stopped being standard when foundries dropped the milling step, not because the metal changed. You can buy that finish new, without the hunt, the cracks or the restoration.

The cheapest route is a machined 12-inch pan at about 5 lb — lighter than most vintage skillets of the same size and a fraction of a collectible’s price. If you want an American-made heirloom instead, the Stargazer 10.5-inch is the closest modern equivalent to what a Griswold felt like new. And if all you actually want is a pan that works, the classic 10.25-inch Lodge costs less than shipping a vintage pan and comes with a lifetime warranty.
