According to U.S. Currency Auctions, if you need a quick buck, that $2 bill could be worth a lot more than the paper it is printed on. The auction site recently updated the values of the uncommonly-found bank note, with some fetching more than $4,500 if it is uncirculated and $2,500 if it has been passed around. Even bills produced as recently as 1995 and 2003 could be worth hundreds of dollars if they were not circulated. According to the United States Treasury, approximately 1.2 billion $2 bills were in circulation, carrying a value of $2.4 billion. That is not much compared to more popular bills like $1 ($12.8 billion), $5 ($14.8 billion), and $10 ($19.6 billion).
