Great rarity, one of the rarest 1/4 thaler of John II Casimir.
Variety with a concave shield with the Vasa emblem on the reverse.
Coin unavailable on the auction market.
On the Onebid website, out of eight listings of this vintage, there is only one of this type, an archive listing from 1997.
Specimen with excellent provenance from the Potocki collection with an ownership mark behind the king's head.
The opportunity to acquire such a rare 1/4 thaler with such distinguished provenance will not occur again for many years to come.
Highly recommended!
