Very rare type of trojak with the Swan coat of arms - treasurer Andrzej Zawisza in front of the head of an ox pierced with a hook by Szymon Lidman.
Rarity confirmed in the catalogs of Iger and Kopicki, while Tyszkiewicz valued it at 20 marks in gold.
A variety with the Swan coat of arms on the left side of the ox's head.
A beautiful, periwinkle piece, with lots of fresh luster, a fleshy disc.
For the best collections - a great rarity in such condition.
