It's genuine! A Four Queens Halloween 2000 "double sided reverse" error chip. Same on both sides with Elvira and LTD 999. NO DENOMINATION - definitely violates Las Vegas regulations for a cash value chip. This UNIQUE chip and many other can be seen at accasinochips.com. Does anyone have it's mate - double sided obverse with Elvira, The Four Queens, and $5 denomiation on both sides?
