The Lublin portrait pennies are a very rare issue, unique in the context of the entire minting of Sigismund III, depicting the king without the insignia of his power - the crown!
Their issuance coincides with the changes that were taking place in this crown mint at the time, which is also reflected in the coins.
This is their first type, distinguished by the absence of Reysner's monogram on the reverse. It was probably minted during the period when Hanusz Eck was in charge of the mint (in an acting role, not signing them with his mark). After Melchior Reysner took over the mint, his monogram was first introduced on them, and then they were changed entirely to pennies with a crown instead of the ruler's portrait.
This type is characterized by a large number of very rare varieties. The present one is a variety with the date in the rim of the reverse (typical for groszes with a monogram, rare for those without it), and an erroneous title of the king. Without the abrevières of the words "king" and "Poland", where we have D G _ REGN _ M D L(by God's grace of the kingdom, Grand Duke of Lithuania).
