I wish I was a bit faster in trying to hit up UD into producing a set of this nature, I had an idea for this about 2 months after Moneymaker won the WSOP Main. I had a 150 card base, with a parallel #/50, and all living WSOP Main champs AU with yr they won, and as an added bonus was going to have some GU, well relatively speaking. All "GU" cards would have casino chips inside from different casinos across the globe, just couldnt figure out the difference in weight to make the packs all seem the same.
Cant remember the exact checklist, but since UD is not going to make this set, I now have some renewed interest in the idea. I think it would be an awesome thing to do, why not everyone who plays poker would be interested, especially in the GU chips, its basically real money as long as you are within some distance of the casino chip you recieve. I will look and see if I have an old spreadsheet around and post again with my checklist and setup. Glad to see that some other people have gotten interest in this.
