I personally think the Sky--- chips are from one the Sky Line Clubs in Billings Montana and the rest are and the Diamond molds have just been changed to Montana from Nevada for I think obvious reasons also, the older mold and name. The Crystal Lounge chips are in the newest circle mold shape I've ever seen so beautiful and wow very awesome chips, So who out there, Michael Knapp, collect these chips ? Now is a good time to pic these up before they are gone and maybe never seen again especially the Crystal Lounge not shown in the Chip Guide without denominations !!! Thanks again and don't let these slip away, very cool set,Torrey
