RR,- Sigismund II Augustus, Grosz 1566, Tykocin with Jastrzębiec coat of arms, very rare

Very rare groshes of Sigismund Augustus from the mint in Tykocin with the Jastrzębiec coat of arms. Deeply minted, however, on a poor quality disc, slightly cracked. In 1566 at the mint in Tykocin, a small number of half-pennies and an even smaller number of groszes were issued with the Jastrzębiec coat of arms of Stanisław Myszkowski. A rare and sought-after coin.
