I used to be in the gaming industry, and helped start one of the boats on the MO river. I am not a chip collector, but have about 1100 chips from the Dubuque Casino Bell. (One of the first, if not the first boat to operate on the MS River.) I have no idea where the market might be for these chips, or an expected value. Any help would be appreciated as to where I might sell them or what they might be worth. Values $100-120 $25-220 $5-280 $1-220 $.50-200. Approximate numbers. All are clay and have the boats picture on them except the $.50. Thanks for your help.
