The two-zloty coin is most likely a souvenir of the war between Prussia and Saxony of Augustus III Saxony, which went down in history as the Seven Years' War, the so-called Ephraimek. A variety with the letters E-C (the initials of Ernest Dietrich Croll) on the sides of the twigs and the 8 GR denomination marking.
The Danzig sixpence is an early vintage, in a variety with a larger bust of the king and the date in line.
