After the 1997 Holyfield Tyson “bite fight”, a scuffle inside the MGM casino resulted in several casino tables being overturned and chips being picked up by the crowd. The casino was closed for several hours and backup $100s were replaced on the tables so no one could try and used some of the old $100s without answering some questions.

Think about it. A guy walks up the cage with a bunch of the “old” $100s looking to cash them in. First, you have to hope you weren’t on tape picking them up, and second, if you said you won them at blackjack, the casino would say - “Let’s go to the videotape.”
