1 Sechsling - Charles Frederick

Charles Frederick of Holstein-Gottorp spent much of the 1720s maneuvering for the Swedish throne and cultivating Russian alliances — he married Peter the Great's daughter Anna Petrovna in 1725 — which left the administration of his small duchy running largely on institutional momentum. The Sechsling, worth six Pfennig, was the workhorse of petty commerce in the Holstein market towns, and these 1723–24 issues fall squarely in the period before Russian court politics consumed his attention entirely.

The duchy's minting rights were a persistent source of jurisdictional friction with Denmark, which claimed suzerainty over Schleswig. Small silver of this type circulated alongside Danish issues of equivalent value, blurring the monetary boundary the dukes were so keen to assert.
