Dennis Berry sent me this link to look up tokens. It is amazing. Here is the info for Black Hawk Colorado
http://www.casino-tokens.com/ColoBlackhawkTokens.htm
Looks like this Hotel had tokens in 1998. He even has some for sale on this site:

This is the info about the fella selling on this website from his home page:
Hi, my name is Dan Wickett, and I've been collecting casino tokens since the early 1990's. I mainly concentrate on Nevada gaming tokens, but have acquired many other tokens and a few chips, from throughout the USA and world. I will be continually updating this web site with new stuff. Unless otherwise stated, all tokens on this website are $1 tokens.
He is a member of the CC & GTCC club.
According to his home page he is out of town until April 28th.

Great to share info among members
