The 1979 10 gr belongs to a small group of several post-war coins that can be collected for several different arrangements of stamp twist. The coin is struck with the stamps twisted relative to each other by about +135 degrees. In beautiful rare condition. In collections of coins 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 number of gems in it, which include the curious minting errors (offsets, twists, reverses) created by accident.
