Obviously the games were small stakes, look at the denoms
Whatever the marker was for, it was obviously deemed to need 100 of them.

Actually, Fred ran the Pan Game also. The order was shipped to him with these chips Im showing. I think Jessie would have been a little young then She didn't move the game. Check timelines in the info here:
