A Renaissance portrait of the king appears on the obverse of the coin for the first time. A very rare trojak minted in only one year. A variety with the eagle's head facing heraldically to the left, practically unheard of on the market, but underestimated in catalogs, where its rarity is estimated similarly to the more popular variety with the head to the right. Tyszkiewicz 50mk, head to the right 40mk. The eagle has its head facing heraldic left, looking at the coin we see the head to the right in the photos. A favorite trojak of Tadeusz Iger. These coins were minted in weak silver the size and thickness of a quarter. Such large and heavy coins, have a content of only 2.32 pure silver, which was obtained from the melting of Świdnica half-pennies. A nice piece for this type of coin. A very rare coin for the best collections.
