Lots of nice silvering.
The shekels with the crowned letters S-R, minted between 1622 and 1623, are coins that current findings attribute to Warsaw. The mysterious mint was known to numismatists as early as the 19th century, but it is still impossible to determine where it was located, in what years it operated and what coins it minted.
A rare variety with the date in ZZ notation, without the crown over the Vasa coat of arms and the corrected letters N.
