How it works

Where the prices come from

We read public eBay listings of Griswold and Wagner skillets as they appear, then check each listing after it ends. A sale counts at the item price paid; shipping is left out because it depends on where the buyer lives.

Which sales count

A sale counts when the listing is one standard cast iron skillet sold alone, with a clear maker mark and size, and ended in the last 90 days. Damaged pieces, reproductions, enamelled or plated pieces, lids, sets and other items are left out. A value is the median of those sales, shown once there are at least 5.

How listings are identified

Each listing title is read into maker, size, pattern number, logo and bottom, and matched to the catalog by code. On a hand-checked sample of real listings, 99.7% of the identities it assigned were correct.
