RR-, Kingdom of Poland, 10 fenig 1917, great shift

Large and thus rare stamp offset. Coin with traces of being stuck in the minting machine. A rare and sought-after destruct. In coin collections of the last century, minted by machine in large 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). A COIN FOR THE BEST COLLECTIONS.
