This is a vintage 10-1/4 inch diameter by 2" deep Revere Ware copper bottom stainless steel skillet, made at Revere's Clinton Illinois plant in 1978. It sits flat with no rocking and has a nice hefty weight to it. The interior is bright and shiny with only the type of hair-fine shallow marks from utensil use and cleaning. The copper bottom has been scrubbed clean and polished. The black Phenolic handle and lid knob have a little fading from dishwasher use.
