Here's how to tell if your old $2 bills are worth anything

• US Currency Auctions are now valuing some $2 bills at thousands of dollars.
• Finding if yours are worth anything is not as easy and checking the mint date.
• The number of bills in circulation, year, and seal color could all impact the value of your bill.

It might be your lucky day if you've ever saved a $2 bill you came across.

Two dollar bills have been in circulation since the 1860s, and have existed in six different currency types, according to the US Bureau of Engraving and Printing. Since 1928, the bills have featured Thomas Jefferson on its face, with his home, Monticello, or an image of the presentation of the Declaration of Independence, on its back.
