These MLBPA Pins were issued as a fund raiser for the fledgling player's union, one of several similar issues that debuted in 1969. Featuring a black & white image and a colorful outer rim, these are prone to handling damage.  This PSA 7 of Roberto Clemente has a fantastic image with the rim taking on a couple of minor scratches on the perimeter. With no 9's or 10's granted to ANY pins in the 60 subject set, this 7 is very high grade indeed.
