A very rare type of coin, occasionally found at auctions.
According to Kopicki (after Dannenberg), this is a coin of Jan of Grystow.
It depicts the head of an ox(bull) in front with a ring in the nostrils, at the top between the horns a ball.
A very nice piece, in an old patina.
Definitely recommended.
Obverse: head of an ox straight ahead with a ring in the nostrils, at the top between the horns a sphere.
