My comments were in theory - not reality !!
I did walk away from the Paris French Roulette wheel one night with my pockets bulging with all the various denominated Jetons - including a $1000 Yellow Jeton that I took to the Cage and cashed in.
I wish I had keep that Jeton - but that's another story. I don't know how many of each denomination they had in the rack at the French roulette table, but I know quite a few "walked off".
I agree with only 300 of each - the game might not run too smoothly with a lot of chips disappearing.
But at $25 each - not to many people are going to "harvest" a stack of 20 for $500.
Take care,
Jerry
