Question
I have a us 20 bill that is printed on one side only. Is there any value to this?

Answer
Hi Karen, Error value depends on type and extent of the error as well as amount of folds or wear and collector demand. This may be worth about $50 or more depending on amount of wear and collector demand.
Current United States currency, regardless of its denomination, can be considered collectible if:
  * There is an interesting pattern in the serial number
  * There is a star in the serial number (Star note)
  * The bill were to have some sort of an error, such as an ink spill, missing the third printing (which includes the serial number and the seal), improper cutting, mismatched numbers, etc.
