The item is present in the collections of Kubicki and Chomiński and in the collection of Karolkiewicz.
The rarity in the Kamiński-Kurpiewski duo's catalog is specified as R8.
A copy with an intensively preserved mint mirror, which is confirmed by the MS assessment from NGC.
The coin rarely appears in trade, but in the presented condition it will be a decoration for any collection, because such a beautiful copy has not been seen on the auction market in Poland so far.
An outstanding and extremely interesting position.

During the first two years of Stanisław August's reign, city mints operated in Gdańsk and Toruń (1765 and 1766). However, these cities were forced to close them. The king intended to get out of the monetary chaos left after Saxon times and introduce a new monetary system. Its basis was to be a Dutch ducat and a thaler minted from Cologne fine (pure silver) in the number of 10 pieces. The reform came into force in 1766. The monetary circulation of the Republic of Poland included beautiful and full-value coins: ducats, thalers, zlotys, groszes and their fractions and multiples. The fact that these were full-value coins resulted in their being taken off the market and melted down into Prussian coins of lower quality. For this reason, the monetary system was improved twice, including: changing the mint rate (1787 and 1794). During the reign of Stanisław August, two state mints operated: Krakow and Warsaw.
