I'm also looking for that Casino Queen and the Sam's Town. Surprised that Casino Queen with the GPI mark is so hard to find since it's a fairly new chip. I've been told by more than one person that the white Sam's Town doesn't exist but according to ChipGuide there are three people out there who claim to have them in their collection. The HSI quarters are very popular with set builders, almost never see them come up for sale. Might post a message over there and see if someone has it. Good group of people, on more than one occasion, folks have sent me a chip I was looking for FREE! Cheers!
