Alexander Jagiellon, Vilnius Half-Groschen – Inverted “D” in “ALEXANDRI”
A very rare variant with an error in the ruler’s name—featuring a mirror-image “D” and a punch mark beneath the “L” in “ALEXANDRI”
This error is highly rated in the specialized Huletski-Bagdonas catalog (rarity grade RIII—equivalent to R7 on the Czapski scale). Known to the authors from only one die (this one!), among dozens of varieties of these half-groszy
A type with Gothic inscriptions on both sides
