Kongo uses the kejsarkrona (plural kejsarkronor) as its currency, which is informally known as the krona (plural kronor). It is the same currency used before the Revolution, and continues to be circulated in Afrika by the Skandinavisk Riksbank. One krona can be broken up into 100 öre copper coins. Different krona bills feature different Emperors (the 20 kr bill features Kristian I, the 50 kr features the legendary Viking King Cnut the Great, the 100 kr bill features Harald II, the 500 kr features Kristina II, and the 1000 kr features Gustav IV Adolph).
Hmm, do you want your currency to mean 'Emperor Crown' or 'Emperor's Crown'? If the former, the name is good, if the latter, you'll want 'kejsarenskrona/kejsarenskronor'.
I have no objection to the kejsarkrona, though I'm dubious anyone but the most insistent monarchist would put Gustav IV Adolph on currency. By the end of his reign he was regarded as a senile, reactionary monarch whose anti-Catholic obsessions had nearly brought Sweden to ruin.
The Workers' Commonwealth uses the republikdaler, which is divided into various units featuring the cog and wheat stalk emblem of the Revolution, a portrait of First Proletarian Mannerheim and sometimes a portrait of Revolutionary figures like the poet and pamphleteer Ibsen or the head of the Steelworkers' League, Andersson Lundeberg.
Well, if Scandinavia in the Kongo has been defined by anything as of late, it would be 'insistent monarchy'.
Vinland has made use of the Vinlandic Krona (in Vinlandic Swedish, it is called Vinlandskrona), commonly refered to simply as the 'krona' (plural kronor) since the early 1870s. Prior to this, it made use of the Scandinavian Kejsarenskrona. The transition took place over several decades, during which the krona was tied to the value of Scandinavia's currency. Imperial coins remained accepted means of exchange until the 1890s, when the Riksdag voted to detach its currency during the economic fluctuations at the very end of Kristina II's reign.
The krona is composed of 100 öre, and coins exist for 1, 2, 5, 10, 25, and 50 öre. Coins also exist for 1, 2, 5 and 10 kronor, with bills existing for 20, 50, 100, 500 and 1000 kronor. A price of 1.25 kronor was traditionally written as 1kr 25ö, but in recent years it has been more common to omit the ö and simply write 1.25kr.
Every coin's obverse face contains the profile of the reigning Monarch, and the year of minting. Thusfar, coins minted between 1872 and 1895 contain the image of Kristina II, coins minted between 1895 and 1899 contain the image of Konrad I, while coins minted since 1899 contain the image of Ingvar I.
