The 'Sidney -O-' marking (WAGNER WARE, SIDNEY, with the O in dashes) is a desirable early Wagner variant. A Sidney -O- skillet in good, flat condition typically sells for about $40–$150, with cleaner examples and scarcer sizes higher. Wagner and Griswold are the two leading U.S. makers, and the Sidney -O- mark carries a small premium over later plain Wagner Ware marks. As always, flatness, no cracks or pitting, and even seasoning set the final price.
