These are two $1 chips from the Great Canadian Casino in Vancouver, British Columbia, Canada. At first I thought the chips were the same. Then I noticed that the chip on the left has a shinny Hats & Cane mold and the other one doesn't. Then I noticed that the numbers above the casino name are different, "0194" on the left and "1089" on the right. And there are other differences as well.

Does anyone know what the numbers signify?
Could the "1094" chip be a Christy & Jones hat and cane mold?
In what years were the H&C CJ mold chips made?
I have never seen a Canadian H&C CJ mold chip, are others known?
