A very nice, rare shellac.
A variety with an incorrect form of writing the denomination - SOLITVS, instead of SOLIDVS.
In addition, with an unprecedented error in the date (twice scored 9, once rotated) - giving the illusion of a 158Z date.
In 1592, the Vilna mint discontinues the issuance of shekels, returning to minting them only in 1614.
Today, early Lithuanian shekels are rare. Against the background of subsequent issues, they represent a good, large coin (over a gram in weight, against an average of 0.6 g).
