I saw that exhibit at the Portland ANA in 2004, and it was spectacular! I still have the brochure they handed out, showing photos of the $100,000 notes (they had a sheet of 32 specimen noted on display ($3.2 million face!) plus they had a lot of old FRNs through $10,000 face, several large size gold and silver certificates, and a lot of treasury bonds worth millions! I only bought a sheet of 4 uncut series 2003 $2 bills though.
