Grade: Near XF, at the bottom of Obv., a small chip on the silver surface near the edge.
Imitation of a sextuple groschen from the Cracow mint, type 667K.3.3 according to Ciura. As a forgery, it stands out for its very good style and the use of punches for letters and images. However, the letters on Rev. are unevenly spaced; in the Obv. legend, there is an error, and not all letter punches are properly shaped. It is possible that it was made by a professional mint.
