For the first time in our offer a 45-degree twist. A total set of 45 degrees, 90 degrees and 110 degrees can be collected. The coin is very rare, a mint piece. In the coin collections of the last century, minted by machine in great quantities, it is not the number of coins that shows the quality of the collection, but the number of gems in it. There is no higher class of gems than low-volume SAMPLEs, and even rarer to them, created by accident, interesting minting errors (offsets, reverses).
