Brunswick-Wolfenbuttel 1732 ducat rev H3029-30066.jpg

This specimen was lot 30066 in Heritage sale 3029 (New York, January 2014), where it sold for $9,987.50. The catalog description[1] noted, "Interesting Harz Mountains Issue Brunswick-Wolfenbuttel. Ludwig Rudolf Harz-gold Ducat 1732-S, MS62 NGC. A beautiful example of this type with light handling and few marks of note, made scarce by the source of the gold rather than the date or variety per se. The reverse includes the legend: EX AVR HERC INF, specifying the source of the gold as being in the Harz mountains. The first mining industry in the Harz centered around silver, supplying the abundant ore that powered the Imperial mint at Goslar in the High Middle Ages. Gold mining came later and produced limited quantities of ore, leading to a number of scarce issues of coinage of Hercynian origin. Ex: "Colonel" E.H.R. Green; Green Estate' Partnership of Eric P Newman/B.G. Johnson." The duke issued four different ducats in 1732, all scarce: KM 822, KM 823, KM 828 (shown here) and KM 821.

Recorded mintage: unknown.

Specification: 3.50 g, .986 fine gold, .110 troy oz AGW.

Catalog reference: KM 828, Fr-680.
