A very rare Lobezhenica denarius with full date.
In Kopicki's catalog, the degree of rarity is R8, which is confirmed by previous quotations. Only 3 pieces were known to Kopicki from the collections of Antoni Franciszek Mathy, Kazimierz Sobański and the National Museum in Warsaw.
An item practically unheard of on the collector's market.
Piece with minor traces of corrosion, but well struck and fully legible.
Highly recommended!
