A 5 zloty with an off-centered core. A type of destruct definitely rarer on this denomination than on 2 zloty, and even rarer on commemorative coins. A beautiful mint piece, strong mint luster, details untouched by circulation. In collections of coins of the last century, struck by machine in large quantities, it is not the quantity of coins that shows the quality of the collection, but the number of gems in it. There are no higher quality gems than low-volume SAMPLES, and even rarer to them, created by accident, interesting minting errors (offsets, reverses).
