Some Dollar Bills Can Be Worth Thousands. This Is How You Can Find One

Dollar bills are essential, but some people might argue they take up too much space in your wallet. It’s hard to argue with that when your wallet is clogged with ten dollar bills, but what if one of those bills was worth thousands of dollars?

Turns out, there are a bunch of websites willing to buy your dollar bills for a lot of money—and it all has to do with the serial number (written in red under the stamp on your bill).

Although the serial numbers on the dollar bills in your wallet are not completely done at random, some of them have some odd numbers in a random order—and that’s more than enough for some people to pay top dollar for them.

According to CoolSerialNumbers.com, there’s a lot of different, weird serial numbers out there. Here are some examples from their “want list”:

-7 of the same number in a row (35555555)
-Repeaters (69696969)
-Double quads (22226666)

So check your bills now—you might be sitting on a gold mine.
