Elbing. August III Tympf 1763-FLS AU Details (Surface Hairlines) NGC, Friedrich Ludwig Stüber as mintmaster, KM113, Dutkowski/Suchanek-438 (R6). A very rare type in any condition, much less this superb presentation for the issue. Slightly mottled tone does little to detract from the surfaces, which although lightly hairlined, bear few marks of note.
Estimate: 2500-3500 USD
