You will receive 2 of these vintage Copper '53 fobs. I'm not sure if they are actually from the 1950's, but, they are quite vintage. I'm don't know what they were intended for either.....perhaps Class of '53? The patina is all over the charts varying from one extreme to the other. Some are very dark, others are lighter, and most have several shades throughout. The weight is heavy(about 3/4 ounce). They measure 40mm(1 5/8") from bottom tip to top of loop. They are 27mm(just ver 1" at widest points).
