An unusually detailed grosz, which is neither an issue from Gubin nor from Grünthal in the literature, first noted in 2020 by J. Chalupski in his book "Copper Crown Coins of August III". Beautifully profiled slender bust in armor with epaulettes decorated with studs, on the ruler's chest the Order of the Golden Fleece, on the reverse a beautiful, richly detailed coat of arms cartouche with beautifully modeled crowns and coats of arms. The issue, due to its similarities to the Dresden thalers (1757, 1763) - characteristic head, armor decoration, in our opinion, should be attributed to the Dresden mint, especially since the minting machines during the Seven Years' War(during which pennies with backdated dates were minted) were transported from the mints in Grünthal and Gubin to Dresden. A great rarity that could be an ornament to a collection of advanced copper coins!
