Funny you should mention the Gilpin. The last time I was in Black Hawk, I didn't remember seeing that building. I hadn't gone inside it but it IS there - just off the main street I believe.
And yes, that is a 50 cent Chipco they are using in the Poker room for some lower stakes games. Next time I'm there I'll have to try to pick up a few more of those. Here are the backs of the Canyon and Gilpins that show a different side of the casino:
These chips are ones I had ordered. I haven't been up there for a few months and missed getting these. The Golden Mardi Gras are brand spanking new though. When I go up to Central City and Black Hawk, I usually hang out in some of the bigger casinos like the Isle of Capri and Fortune Valley. Unless there are new chips that I'm aware of, I typically don't go to the smaller casinos there much. The Colorado Central Station is now being joined to the Isle of Capri with a huge new overhead walkway - should be open soon. Lots of activity going on. The Mountain High casino has been bought out by Ameristar Casinos and is redecorating now and will soon re-open under a new name (and with some new chips as well!) Hope to go up there for that re-opening.
