An undescribed variety in the specialized catalog of "Crown halfpence of Wladyslaw Jagiello".
Distinguished by the very rare spelling of the ruler's name, without the last two letters (WLADISL instead of WLADISLAI).
Sebastian Pawlikowski notes two varieties with WLADISL for this type (XIII), both assigning a degree of rarity to UN (from unique), but not linking this reverse.
The type dates to 1408-1410, and is characterized by the absence of additional mint marks, a straight crown and Classical (instead of Gothic) A letters.
