The clay chip may were well be a LAY bet on a crap table which is still used here in vegas, most of the time the chip is more like a lammer. However the other chips are catalin which came from me. I had a game set which I brokeup a few years back and their were 400 of these LAY chips in the set. The same initials were stanped on the game case. Hope this helps a little. Mike Spinetti
