There is an auction up for a Hard Rock Big Daddy Roth Set item # 220701560032. I havent seen this set for sale recently but the last time I did it sold for around $300 to $400. The seller says they bought this set in the gift shop. I thought they didnt sell "real" chips in the gift shop but only from the cage. Is this the set that Big Daddy Roth autographed or is it something different?
