Steve, I did some rough calculations using the numbers you posted & assuming that there are 7 colors of chips at each of the roulette wheels with each wheel having it's own chips, you would have to harvest 1,404 give or take a few chips, in order to get every one currently in use. That's a tall order, even for the 2 or 3 dedicated guys who specialize in these sorts of things! I have a feeling that Susong has already made a trial run.<g>
