I have a 25-cent chip that I'm trying to ID. It says "Rainbow" on it, and has mountains pictured in the background, and a rainbow w/ pot of gold (The word 'RAINBOW', in all caps, is written curved around the rainbow).
The outside edge of the chip is red, with teal-green bands at the top, bottom & both sides.
I think that it's from a defunct casino. Anybody know where this is from?
