RR-, 10 gold 1965, Copernicus, DESTRUCT - DOUBLE DIE, first time on onebid

A rare variety with a doubled inscription of POLSKA RZECZPOSPOLITA LUDOWA. A great rarity, destructs of copper-nickel coins from the 1950s and 1960s are virtually unheard of on the market. First time on onebid.
In coin collections of the last century, struck by machine in great quantities, it is not the quantity of coins that indicates the quality of the collection, but the quantity 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).
