$5 1969-C FRN MISSING FIRST PRINT BLANK BACK ERROR PCGS Unc 62

Blank Back Errors have been exceptionally difficult to locate recently! In fact, we only have two at the time of writing...this example and an ultra-rare $2 1976 FRN missing first printing error which is priced around $9k. This note shows no evidence of green ink on the back and entirely missing the first step of the printing process before the sheet advanced to the remaining printing and cutting procedures. Preserved in Unc.
