There are sure a bunch of colors for this drink token. I was fortunate to be able to get 17 different from another collector, all nicely identified on the cardboard. If you recognize your neat lettering on these holders, remind me of who I have to thank

I have found one more since, making a total of 18. I haven't tried to get all the holey and unholey versions, as I can't imagine why the casino would have ordered them both ways. Also, since these are molded plastic and not struck tokens, I doubt there is any intentional aligning of the marking on the obv/rev when the molding die is assembled.

Here's what they look like.
