A very rare coin, minted with a 180-degree inverted stamp. The eagle on the obverse is upside down compared to the images on the reverse - the so-called REVERSE. A beautiful copy, mint gloss, details untouched by circulation. In collections of coins of the last century, minted by machines in large quantities, it is not the number of coins that indicates the quality of the collection, but the number of gems contained in it. There are no higher quality gems than low-volume TESTS, and even rarer, interesting minting errors (shifts, reversals) that occurred by accident.
