A rare variety for this vintage of Bydgoszcz trojaks.
Minted already after the introduction of the mandatory mint mark (in this case the letter B from Bromberg), but before the simplification of their reverses. Before the removal of the initials of the Grand Treasurer of the Crown (IF) Jan Firlej.
Distinguished by the initials placed above the date, flanked by a rosette and the letter B.
Rarer than the degree of rarity in Iger would indicate.
Nice state of preservation. Obverse stamped with a long-used stamp. Light rubbing in the scarcity area, additional scratch at the bottom of the portrait. Nice luster. Light patina.
