I have two chips from The Christiania. One has a serrated edge and the other a plain square edge. They are the same on both sides. My question is... why would a casino have no value chips with these two different styles. I always thought the different colors must have been roulettes, but rounded serrated edges would seem a little more difficult to handle as roulettes than a square edged chip. Does anyone know what games The Christiania had? Are there value chips from that casino? Thanks for any info.
