Very rare Prussian thaler of George Wilhelm.
Variety with half-figure in profile.
The coin is defined in the Kopicki catalog as R4 rarity which we believe underestimates the real level of rarity for this particular coin. In the world's largest auction archive Coinarchives over many years, only 13 records.
Obverse: half-figure of the elector facing right in armour, with a scepter resting on his shoulder, holding a helmet in his hand
