RRR-, 5 zlotych, 2017 COP. DESTRUKT, ONE COLOR (resembles a proof)

An extremely rare type of 5-złoty coin blanks. A hole was punched centrally in the outer ring; the center was not then punched out, and this ring was subsequently placed under the die, where a coin was correctly struck, resembling a trial strike in a different metal. The central hole shrank significantly under the pressure of the press. A coin virtually never seen on the market. Most 5-złoty coin blanks found on the market are coins with a centrally punched hole into which the inner ring was poorly fitted. Excellent condition, the highest grading grade in the world (for a coin blank). A COIN FOR THE FINEST COLLECTIONS.
