Until 1868, Sweden had always minted ducats as golden trade coins. 1 ducat equaled 8 riksdaler and 25 öre. From 1868 to 1872, however, the carolin replaced the ducat. 1 carolin equaled 7 riksdaler and 10 öre as well as 10 French francs. And since at that time the French currency was on a par with the currencies of Switzerland, Belgium, Italy and Greece, the carolin was meant to serve as trade coin in these countries also. However, with a weight of 2.9 grams, the carolin was considerably lighter than the 10-franc coins, which weighted 3.2 grams. It was thus only unwillingly accepted and soon given up again.
