I don't know anything about the Showboat. I am guessing I have only been alive for half the time this chip sat in the sellers jewelry box...How long was this place open? How many of these chips are believed to have survived this long? How can anyone proove that? Are the other denoms out there too? Was there some kind of proof that the chips were destroyed after closing the doors since many casinos seem to NOT destroy the remaining chips (even when they pay someone to destroy them)?

Thanks,
Dave
