Sweden 1854-AG ducat Fr-90a
This specimen was lot 34284 in Heritage sale 3106 (New York, January 2023), where it sold for $1,680. The catalog description[1] noted, "Sweden: Oscar I gold Ducat 1854-AG MS63 NGC, Stockholm mint. With initials AG for mintmaster Alexander Grandinson. Variety with large 'AG' initials. Proudly lustrous and flashy, the raised motifs graced with a dusting of frost." This type was struck 1845-59 and is the first Swedish ducat that can be called fairly common. Large and small "AG" varieties are noted for the year.
Collecting Swedish coins is complicated by the multiple currency reforms the country underwent during the period. In 1798, 48 skilling = 1 riksdaler species and 2 riksdaler species = 1 ducat (the ducat was the same size as the coin shown here and the riksdaler species was 29.36 g, 0.878 fine silver). In 1830, 32 skilling banco = 1 riksdaler riksgald and 4 riksdaler riksgalds = 1 riksdaler species (the riksdaler species became 34 g, 0.750 fine silver). In 1855, the skilling was dropped and 100 öre = 4 riksdaler riksmynt = 1 riksdaler species (the riksdaler species remained unchanged). In 1873, the riksdaler species was dropped and 100 öre = 1 krona (the krona, at 7.5 g, 0.800 fine silver, was slightly smaller than the old riksdaler riksmynt). The system adopted in 1873 is still in use today, the Swedes having recently declined to adopt the euro.
Recorded mintage: 20,000, a common date for the type.
Specification: 3.49 g, 0.976 fine gold.
