Someone was looking for a purple Diamond level Treasure Club card from the RichMan Casino in Black Hawk CO and at the time I did not have any extras/dupes. The Colorado slot card collection I recently acquired has given me a whole new batch of duplicates, including a bunch of rarer cards. As such, I now have an exta Diamond level Treasure Club card from RichMan. And, in fact, I have a full set of blanks of all 4 levels. If anyone is interested, contact me via email.
