$50 1981-A FRN, Fr. 2121-K Offset Printing Error PMG Ch Abt Unc 58

A well-preserved small head fifty that certainly presents like a problem-free Unc example. The back to face offset is quite bold and nearly complete with the lower right corner remaining unaffected by the mirrored impression. Comment of 'minor foreign substance' of which we can't begin to guess where or what this grader may have seen prior to encapsulation.
