I picked up a box of playing cards at an estate sale today. There must be a couple hundred different designs. I'm guessing there was a connection to USPC Co. One of card backs is very similar to a chip I have from the Penn Athletic Club. There is one noticable difference. The chip has a five point star with PAC on it. The card has a six point star. Question is.... Does that difference make the items from a totally different place.
