1/2 Daler / 8 Skilling Banco - Charles XIV Johan Pattern strike

Charles XIV Johan — the former French marshal Jean-Baptiste Bernadotte, elected crown prince of Sweden in 1810 — spent much of his reign attempting to rationalize a Swedish monetary system that had accumulated decades of parallel currencies, banco valuations, and competing riksdaler denominations. This 1830 pattern was produced during active internal debate over currency reform, testing denominations that might bridge the old banco system with a more coherent decimal structure. The reform would not fully resolve until 1855.

The dual denomination designation itself — struck to satisfy two overlapping accounting systems simultaneously — is the coin's most historically telling feature.
