I've got a 2004 $20 that is a pretty good birthday note - its EK20030207A and I've got a $1 2003A that is G19830430I. Interesting numbers, but are they worth anything? I looked on completed
ebay auctions and didn't see any that had sold. Should I just put these bills to good use and buy some halves with tnem or is there someone that would buy them?
