Fr. 2182-B. 2006A $100 Federal Reserve Note. New York. PCGS Currency Extremely Fine 45 PPQ. Type II Inverted Overprint on Back.A popular error type on very bright and fresh paper. Unlike the more common overprint on back errors, these inverted overprint errors on the back are actually a dual error. Such an error is hardly encountered due to the currency sheet having to enter the overprint press with the backside closest to the bottom of the press, resulting in the striking error as being offered.
