A truely unique coin.
Piedfort of the Danzig 3 groschen of Augustus III from 1755, minted in pure silver on a slightly wider planchet.
Three groschen minted in pure silver are very rare coins, but piedforts are considered to be extremely rare, if not unique.
Uncirculated coin with sharp details and lustrous surface. Natural patina.
The only specimen of the piedfort graded MS by NGC.
