Thanks for the kind words Bill.

I love the Marciano piece. His signature is much better than my scan depicts.

However, my favorite boxing item is my full-sized blackjack layout from the Holyfield/Tyson II "ear bite" fight. It was presented to Holyfield by the MGM. Unfortunately, when Holyfield went bankrupt, much of his possessions we sold at auction. I was able to pick it up.

Regarding the D.B. Cooper bill, I also have another interesting item associated with it - an original wanted poster of Richard McCoy:

Many think he was D.B. Cooper:

One theory is that McCoy was D.B. Cooper, and in the first hijack he lost the $$ somehow during his descent. He survived the jump but without the money. He tried it again. That could explain the Cooper bills found years later and why no other Cooper bills showed up in circulation.
