I don't know that one, but nice. Easy guess is, casino promotion. That doesn't mean I'm right, but as a give away, or special use, it would make sense. If you have two, drop me a note?

It could have been a bingo marker, as the WI casinos started as bingo halls and then added games in their challenge for the right to have slots and live gaming. The WI casinos also had free play and match play, that were much like that. They handed them out at the door and nothing on the chip said what it was. The colors changed. That's why I'd lean towards promotions.

Oh and yes, that was the name they used early on, before they changed to the Ho-Chunk Casino Wisconsin Dells, they started as as Ho_Chunk Baraboo.
