This vintage 9-1/2 inch diameter by 2" deep Revere Ware copper bottom stainless steel skillet with lid was made at Revere's Clinton Illinois plant in 1995. It's super clean and shiny, with only the normal hair-fine shallow cleaning and light utensil marks inside. There's a small, shallow bump at the center bottom of the pan from manufacture but it doesn't keep the pan from sitting flat, whether on a smooth glass stove cooktop or a coiled burner.
