Cadillac Hubcap Emblem Badges (2) 60's/70's (?) Man Cave Garage Art Collectible

This is a pair of used Cadillac Hubcap Emblems. Unfortunately there is no part number listed. My guess is that they are 1960s or 1970s. The one with the square on the back weighs 2.5 ounces. The one without weighs 3.2 ounces. Bin 126
