2013 5 Dollar Bill With Serial Number That Has Repeating Numbers

This is called a QUAD DOUBLE when a serial number has four sets of doubles
(pairs of numbers) (11223344). Condition generally contributes a lot to value (so finding them in uncirculated new bills increases value potential), but its a great find, worth keeping, and there is interest among many collectors for these.

The name is sometimes also confused with a double quad serial number, the first four digits are all the same and the last four digits are all the same, but a different number. Examples are 88882222 and 55559999.

Its also possible to have a repeater serial number where the second four digits are a repeat of the first four digits. This would have been the case if your serial was 33773377 or 33993399.

Needs to be 33773377, or 33993399, to have any real value to a serious collector.
Still, as a lower denomination Bill, if it had been in CFU (Crisp Flat Uncirculated), it would have been a keeper,
but too far gone in it's current condition, unfortunately.

Thanks for the feedback everyone and the links John. It's definitely a keeper for my starter collection. IF I ever try to sell it, it may only fetch a few extra dollars from a beginner like me but that's ok.
