This is not only a very rare variety of Poznañ trzeciak 1626, but also one of the prettiest representatives of this vintage we have seen.
Beautiful for a late Poznañ thirds. Lots of natural surface silvering. With uncirculated detail.
A variety described by Edmund Kopicki with a grade of rarity of R7.
Distinguished by two coat-of-arms shields (of Poland and Lithuania, instead of a single, simple shield), with the date only in the rim of the reverse.
