It belonged to my mother, who died a few years ago at the age of 97. The marks on the bottom of the skillet include "No. 6," the word "Griswold" in a circled cross above "Erie, Pa." and the number 699. I don't want my kids selling the skillet for $1 at a garage sale. A. Skillets and other cast-iron cookware made by the Griswold Manufacturing Co. are collectible. Tell your children not to sell the skillet for $1. Griswold made cookware from the late 1800s until the 1950s. Skillets came in various sizes and styles. Yours, the No. 6 skillet, made using Griswold's pattern No. 699, sells for $15 to $20.
