Very rare variety of 1949 brass zloty - without the concave PRÓBA inscription.
The brass pieces created on the initiative of Władysław Terlecki and PTAiN were made in an edition of 100 pieces, but only on individual pieces the characteristic PRÓBA inscription was not struck, which is confirmed by their few auction listings.
Mint condition, with spots of tarnish, background mirror.
Mintage unknown.
Brass, diameter 25 mm, weight 6.66 g.
