Your $2 bill could be worth thousands

(CNN) – If you have any old $2 bills laying around, they could be worth thousands.

Some newer bills, such as those printed in 2003, could have significant value.

One $2 bill from 2003 with a very low serial number recently sold at auction for $2,400.

And it later resold for $4,000.

That’s according to Heritage Auction, the largest auction house in the world that deals with currency.

The auction site, U.S. Currency Auctions, estimates that uncirculated $2 bills from nearly every year up to 1917 are worth at least $1,000.

$2 bills with red seals can sell for $300 to $2,500.

And those with brown or blue seals can sell for hundreds.
