A lot of great responses and stories...I really like yours Archie, about the pool.....Also, yes it does look like a pully of some sort....Maybe it was gouged, (spelling) oh well, to fit into something......I hope that whoever did this to these chips will read this and not do it or try to pawn it off again....Thanks everyone....
Maybe it was a slabber....hehehe...before anyone starts in, I believe in slab free....
