Fancy Serial Numbers

First, there are a lot of factors that come into play when determining the value of currency.

Condition, the type of error or variety in the piece, the aging of the bill or coin, and so forth. With this in mind, just having a collectible or fancy serial number does not mean that old, torn bill is worth much. Now, if you are able to maintain higher condition of the bill and the item has a very unique serial number, you could be sitting on thousands of dollars!

Also, the denomination of the bill is factored into the value as well, but plays less of an impact than you would imagine. The higher value bills will be worth a comparable face- value increase than lower face- value bills.

So, a $100 bill with a radar repeating serial number will be worth a similar increase to worth over its original $100 face value as the $5 bill with a radar repeating serial number. Of course, both bills would need to be in comparable condition.

However, the same fancy serial number on a $100 bill won’t make it worth $2,500.  A $100 bill is already worth $100, so it takes a really important serial number to add a lot of extra value there.  It would be very costly to collect $100 bills just because of their serial numbers.

Star Note Bills with Fancy Serial Numbers

Solid Serial Number – All One Number

Low Serial Number – Two Digits or Less

Trailing Zero Serial Number – Seven Zeros after Number

Ladder Serial Number – Sequence of Consecutive Numbers

Radar Serial Number – Reads the Same Both Ways

Flipper Serial Number – Reads the Same Upside Down

Repeater Serial Number – Two Numbers Repeated

Binary Serial Number – All Zeros and Ones

Stand Alone Serial Number – Number Surrounded by Zeros

Here are examples of each:

    just my opinion, but the g55119900 is the only one I’d set aside.
    I have two renters that pay me in cash, so I asked them to give me rent in all singles. they must think I waste the money at stripe clubs…LOL

      ” ..after that comment remember to put latex gloves on while searching bills….”
      That was a very funny comment!

      Yeah I agree too, keep the G55119900 due to the serial number being decent. I’d set that aside too.

    I also have 2 $1 bills that I don’t think are too unusual with their serial number, but I’m going to run it by you. One is K36663001A and the other is K88994420E. Probably nothing, right?

    Do you want a rare note I got one for you. I found a 2013 $20 note which is a double-digit mismatched serial number error verified by PCGS currency. I put it up for auction with Stack’s Bowers auction house for the Ana Denver World’s Fair of money auction on August 4th 2017. Serial number MB 54552690/54547690!!!! PCGS graded 40 which is extremely fine condition. What do you think of that if you can find one of those good luck. Mine is the only one out there
