RRR-, John Casimir, Thaler 1649, Gdansk, GEDANESIS error (instead of GEDANENSIS), R7

Coin with an obvious error in the obverse inscription on the reverse. In the name of the city, missing the letter N, GEDANESIS instead of the correct form GEDANENSIS. Such errors are extremely rare on thalers, the production of which was subject to strict quality control. Attractive piece, very good overall presentation. For the best collections!
