The two dollar bill goes back to 1862, when it was first circulated. Printing numbers decreased in the 1950s. It continued to 1966, when its class of notes was discontinued.
It was renewed in 1976 as a bicentennial federal reserve note, with different illustrations. Because printing numbers are low, many stories became associated with it.
It was considered a 'bad luck' bill by many.

The last series printed was in 2006, when demand started to increase. It continues to be a circulating currency denomination. For some reason, never popular with businessmen.
