Very nice luster.
This is the rarest vintage of the five years of the mint's operation, which for years was considered to be Cracow's. Incorrectly, as Slawomir Dudek discussed more extensively at our National Numismatic Forum, presenting a number of arguments refuting the attribution initiated by Marian Gumowski. There is currently a debate as to which of the Crown mints could have minted these coins. One hypothesis is Malbork, as Cezary Chelchowski wrote about in an excellent article (BN 2/2021). Another theory is the mint in Wschowa.
