Sigismund I the Old, Half-Groschen, 1512, Vilnius—errata, mirror-image "D"—rare

Sigismund I the Old, Half-Grosz 1512, Vilnius – error, mirror-image D – rare
A variant featuring the Pogoń without a sword sheath on the obverse and an eagle with its upper feathers pointing toward the eagle’s head on the reverse.
A punctuation variant with a slash after “MONETA” and a colon after the date.
Error—the letter “D” in “…SIGISMVNDI” is a mirror image—rare.

Condition: 2-/3+
Slight missing mint marks on the edge, but the coin is very well preserved. A rare and underappreciated error—the letter D in …SIGISMVNDI appears as a mirror image. The coin is rare and quite difficult to find on the collectors’ market. An attractive piece for specialized collections.
