I picked up a few old chips in a shop over the weekend. I'm sure every antique chip collector has this PC-RA chip. I noticed on a few of them there appears to be a double image in the in the center area of the chip. I guess a double stamping of the mold. It's only on one side of the chip similar to the "flying turf" on the golfer chips. The effects are quite noticeable. The monkey has an extra finger on his left hand, the cat's eyes are missing, there appears to be extra cards and chips on the table. Do others out there see this variation often?
