Great Britain ND (1980-84) P-379b PMG Choice Very Fine 35 10 Pounds (Offset Printing Error)
A wonderful offset printing error, with the mirrored image of Queen Elizabeth II appearing on the reverse, as well as the other design elements. This is caused when the ink on one sheet of banknotes has not properly dried before the next sheet is put on top. Very scarce and one of the more spectacular British errors.
