You may want to check to see if you have any $2 bills in your wallet. U.S. Currency Auctions estimates that uncirculated $2 bills from 1890 could sell for up to $4,500, and uncirculated bills from nearly every year between 1862 and 1917 for at least $1,000. Newer bills could also have significant value, as a $2 bill printed in 2003 recently sold at an auction for $2,400. Learn more about if your bill has high value at the link in our bio.
