... is that the words "Casinos Austria" and the denomination "100" are clear (see through) and the two sides are randomly oriented. Hence, each chip is slightly different in appearance from each other chip (particularly when held up to the light) ... unless, of course, you can find two in which the random orientation is exactly the same, in which case the chips would appear identical.

One of my favorite chips, which I got from Ulf Helmke of Germany (and a friend from the CompuServe Collectibles Forum -- haven't heard from him in at least five years).
