All serial numbers are unique (or should be!)Ī few weeks ago, my daughter and I went through about $300 worth of $1 bills looking for fancy serial numbers. What makes a serial number “fancy?” Being one-of-a-kind isn't enough, obviously. Fancy serial numbers are (literally) a numbers game While many currency errors are found by the Bureau of Engraving and Printing employees before they ever see the light of day, every bill should have a serial number. Another way (that might be easier) is by finding cool serial numbers - serial numbers that are special in some way. There are lots of opportunities to cash in on your cash.įinding currency errors is one way.
