Usually I end up mailing out any error chips I end up with! Like the 1998 Hard Rock July 4th chip I sold for $8 & found out about it later! At least that made me start looking through the chips as I bought them. This is no Hard Rock, but an error chip none the less. As you can see from the scan below the Holyfield/Ruiz $5 chip is different on both sides. One side has the date of "March 3, 2001" with the other side having "Las Vegas, NV". The error chip I have has "Las Vegas, NV" on both sides & no date. Does anyway have one with the date on both sides? Andy - Las Vegas
