Ray O. writes: I have a mint condition US dollar bill that has the serial number printed on the back side and no serial number on the front. I also have the dollar bills with the serial number before and after this one which are on the correct side. I received these bills from a bank in a bundle of 100 bills in sequencial serial number order (i.e. new bills). I also have the band that was around the bundle but it’s not in good shape. My question is how rare are these bills and are they worth much as collector items. I put them away once I saw the miss print and have tried to keep them in perfect shape with minimal handling. Any insight to what I found would be appreciated. Thanks, Ray O.
You have a “third printing error” – overprint on back.
U.S. currency is printed three times. The first printing is the back of the note, the second printing is the front, and the third printing (called the overprint) consists of the serial numbers and Treasury seal. Your sheet went into the overprint press reversed and the third printing was put on the back instead of the front.
Current market value for this type of error is approximately $100.
