Zurich. Free City Taler ND (circa 1560) MS64 NGC, Dav-8783, HMZ-2-1123b. A wonderful example of this "Stampfer" taler, so named after the mintmaster at the time, with gray tone over bright underlying silvery luster. A touch of granularity blends in the obverse edges between 1 and 4 o'clock, but otherwise the surfaces are worthy of the "Gem" moniker.
Estimate: 1500-2000 USD
