RR-, 50 zloty 1981, Ladislaus I Herman, DESTRUKT - DOUBLE DIE from the top

A rare variety with the date and denomination doubled at the top. In collections of coins of the last century, struck by machine in large numbers, it is not the quantity of coins that indicates the quality of the collection, but the number of gems in it. There is no higher class of gems than low-volume SAMPLEs, and even rarer to them, created by accident, interesting minting errors (offsets, reverses).
