while out today, went to money exchange place, I only had 1 US100$$ with me, and they would not exchange it because the year was 2001 and the serial number started with "CB", they will exchange all 100$$ notes except the ones that start with "CB" (and they will not exchange any 1996 100$$ notes) so off to the ATM machine again using my prepaid travelers check on a card thingy.
