Extremely rare, even unique variant of the early Bromberg coin of Sigismund III Vasa without a denomination.
On the reverse, in addition to the coats of arms of the Crown, Lithuania and Snopek Vasa, there are also the coats of arms of Lewart - Jan Firlej, Róża - Herman Rudiger and Radwan - Stanisław Cikowski, the owner of the Bydgoszcz mint.
The rarest type of 6 groschen among those listed in the Kamiński-Kurpiewski catalog, the other five of which received rarity grades from R6 to R7.
There are only two listings for this type of 6 groschen in the Onebid archive, with the last one from 2019, where it was sold for PLN 29,900 .
Coin missing from most collections.
Plenty of mint bloom.
The chance to purchase such a rare 6 groschen with such distinguished provenance from the Potocki collection may not happen again for many years.
Obverse: head of the king facing right, wearing a crown, armor and a ruff
