Prussian coins of Frederick II imitating the sixpences and orts of August III were issued in 1755 and 1756, and were minted in Königsberg (E) and Breslau (B). In Prussia, circulation of these coins was prohibited because they had a lower silver sample. Agents of Frederick II illegally issued it in Poland in exchange for full-value coins. Only on the 1756 sixpacks minted in Königsberg (E) is the bust of Frederick II likened to that of August III. This is described in detail by Kalkowski "Thousand Years of Polish Coinage" p. 112. Olding "Coins of Frederick the Great" item 213 - in the description " The portrait depicts the Saxon prince Frederick August II, who was at the same time king of Poland called August III". Due to the small issue of these coins, a very rare item. An exceptionally beautiful numismatic
piece, the only nicer
piece offered on the auction market is a coin sold 7 years ago at the 62nd WCN auction for 3136 zloty
