Good very fine and a very rare variety.

Ex Spink America Auction, New York, December 6-7, 1999 (lot 657 part), from a private collection formed by a pair of Polish brothers and sold by auction in New York.

An obverse die apparently not reported used on a reverse roughened without granulation as appears on many other published coins. Hardwick notes various symbols in the obverse field, this example is without such a symbol.
