A very rare denarius, noted only in the book "Iconography of Piast coins" by Witold Garbaczewski.
A mysterious issue known from only a few pieces, attributed to Lestek Boleslawovic or Casimir the Just.
High legibility for the type, old patina, disc loss.
Distinctive minting, obverse struck deep, reverse shallow.
Definitely recommended.
obverse: bust of the ruler straight ahead, in his right hand he holds a sword, his left hand is outstretched in greeting, around the inscription
reverse: bust of the ruler straight ahead, in his right hand he holds a sword, his left hand is outstretched in greeting, around the inscription
