There’s a good chance you have at least one dollar bill in your pocket right now. It’s likely that you don’t think much about your US dollar bills. These days, you can’t get everything with just one dollar. That being said, it might be a good idea to look over the one-dollar bills you have in your hands more carefully. This is possible: if they have a certain serial number embedded in them, they might be worth a lot more than one dollar.

A site called CoolSerialNumbers.com is making a lot of money right now by selling “fancy” serial numbers. What kind of bill you have and whether it has one of these complicated serial numbers will determine how much money you can make by selling it to the website. In your search, look for these things:

When the Federal Reserve issues notes, they have seven numbers that repeat, like 09999999, 18888888, 19999999, and so on.

There are seven of the same kind on one-dollar bills from the Federal Reserve, such as 00010000, 00090000, 90999999, and so on.

On Federal Reserve Notes of $1 value, like 01111110, 10000001, 80000008, and other notes with similar numbers, there are pictures of super radars.

Super repeaters are notes that the Federal Reserve has released, such as 67676767.

Notes from the Federal Reserve that are worth one dollar each have numbers like 11110000, 44440000, and 88880000 on them.

To make things even worse, that’s not all. Check out the “Want List” part of the website to learn more about the extra serial numbers they are looking for right now.

It’s amazing that something as small as a crumpled dollar bill can actually give a lot of money. It’s also amazing that this can happen. People, take a look at your financial position! Today might be a lucky day for you.
