found me a 2006 $1 with an interesting S/N today F22700226R I realize its not real anything special like if it had been 22700227 or a 22700722 but its better then anything ive yet to find other than star notes. So I thought id share it with you all, and sorry no pics dont think it be worth the effort anyway.
ikandiggit is right. There are possibly more notes in cirulation that can be deemed as having an interesting serial - then those will utterly normal serials. Thats why i think its so funny for all those ebay sellers hyping up their auctions of normal notes as fancy serials. Keep looking - you will find what your looking for!
