for a penny, back in the 1950s early 60s. The picture
has an enamel like finish and the frame looks like metal
but probably made out of plastic. One has a silver
finish the other Gold. Most gumball vending machine
rings sell for about $10. these tiny 1 inch lockets are
a lot more rare, and could sell for the $50.+ range.
