Lots of luster, good minting quality. Beautiful.
Definitely an above average piece.
First vintage of the half zloty.
The 2 silver penny was a denomination introduced as part of the monetary reform of February 1766, representing 1/2 of a zloty, whence its common name.
Variety with eagles of pattern 2, seven leaves of laurel (not described in Parchimovich's catalog for these eagles).
