RRR-, August III, Shelag 1763 Elbląg, destruct, obverse positive, reverse negative

An uncommon type of destruct with a non-centrally beaten obverse and reverse in negative[sic!]. A minting error practically unknown from coins of other types, unlike the typical in this group of destructs: convex obverse - concave obverse or convex reverse - concave reverse. A great rarity, both an ornament of the collection of destructs and an interesting addition to the collection of Elblag or Elblag coins.
