I guess you know the 50c chip is pretty scarce, Lee. I got mine several years ago for $300. I've seen a scattering on ebay the past year that seem to always go at $100+. You may not want to go for multiples of this one.

Some of the other denominations are available in quantity, either from the TR King disposal or the change of chips at Tropicana a while back. I don't collect them, so don't have specific knowledge of any of the others.

Good luck!
