One of the rarest varieties of Breslau ducats of the time of Emperor Ferdinand.
Variety with an error in the titulary, abbreviating the word "Austria" (there is Archidux AVT instead of AVST - the letter S is missing).
Described by Jaroslaw Dutkowski with a degree of rarity of R8 (2-3 pieces known), known to him only from one auction listing in the world. Offered for the first time in Poland.
Emperor Ferdinand III, upon assuming the throne in 1637, began issuing coins at all of his subordinate mints. One of them was Breslau, which issued the first gold coins already in the year of his coronation. These were ducats and half-ducats.
The first ducats were characterized by a portrait with an open crown. A new type of bust, with a closed crown, was not introduced until 1639, of which this ducat is an example.
Its Breslau character is evidenced by mintmarks - the Swan of the mint's lessee, George Richart, and the initials M-I (Michael Jan) of the mint's warden.
Matted/cleaned near the portrait. Mirror preserved in the rim and beautiful on the reverse.
The only Wroclaw ducat of Ferdinand III with an error.
Gold, diameter 21 mm, weight 3.47 g.
