until after I check out in June

Comments about the auction. All Nevada gaming chips must be redeemed at face unless appropriate rules are followed in which notice is given of intent not to redeem. I don't have my copy of the Nevada gaming rules in front of me but they would contain the number of days or months for which notice must be given. In the case of the Harrah's chips, they are still current. But $100????

Allan will have to answer your question as to "error" chip but I wouldn't call them an error chip. Harrah's merely determined to issue a new set after learning of the change of the date of the Super Bowl and after having already ordered the original chips.
