RR-, 50 zloty 1981, Wladyslaw Sikorski, DESTRUKT - DOUBLE DIE, above the date

A rare variety with a doubled date and denomination. The variety described in the latest recent album publication by Janusz Parchimowicz 2022. In the coin collections of the last century, machine minted in large numbers, it is not the number of coins that indicates the quality of the collection, but the number of gems in it. There are no higher class of gems than low-volume SAMPLES, and even rarer to them, created by accident, interesting minting errors (offsets, reverses).
