John I have only seen a few of these and was lucky enough to pick up these examples. I am sure there are a hand full out there but maybe thats all? Anyway I was, I consider fortunate to pick these up and they are so cool!!! Bringing them to show,sell,trade? Wish I knew an exact value at least at the moment to put on them? I know what they have sold for but what are they really worth.Would hate to sell them and find out that was all there were and the value go way up,plus I really like them for the history,beauty,where they are from etc. just an awesome chip and such a cool design with the denomination all around the rim and the Duck with the cards,being from a Show Boat,so much to like about these chips,Any help on these appreciated,Torrey
