10 Kronor Sweden

The Swedish 10 Kronor gold coin, first struck in 1876, featured a portrait of King Oscar II that remained largely unchanged for decades, symbolizing the era's political stability.

This coin weighed 4.8 grams and contained 90% gold, making it a practical medium for high-value transactions in the Scandinavian Monetary Union. Variations occurred with different monarchs' effigies, from Oscar II to Gustav V, reflecting Sweden's royal successions. Mintage figures vary by year, but records from the early 1900s show production often exceeded 100,000 pieces annually to meet demand.

Not every specimen survived intact; wear from circulation was common, especially during economic upheavals. As for myths, I've heard tales of these coins funding polar expeditions, but that's likely exaggeration—most just sat in banks. Collectors might quibble over that.
