A typologically rare coin.
In the last years of the reign of Augustus III Sas, in a country flooded with counterfeit coinage of Frederick the Great, three Polish cities - Gdansk, Torun and just Elblag - decide to defend their market. They start issuing coins. In the case of the Elbląg mint, these are first shekels (starting in 1760), which are joined by other denominations in subsequent years. Elblag issues its first sixpences in 1762, at a mint under the management of Jost Carl Schröder, whose initials I.C.S. are affixed to them.
A variety with a narrower royal bust dividing the legend at the bottom.
On the reverse is a narrower, oval shield of the coat of arms, in an ornamental cartouche. The legend began with a rosette.
