The currencies of the three countries are all called "krona", but they are not the same krona. There is a price difference between them.

Of the four Nordic countries, only Finland uses the euro, and all other countries use their own currencies.

The "Orr" you found above is actually our "score", 1 yuan = 100.

It seems that Danish krona is the most valuable now, followed by Norwegian krona, and Swedish krona is the lowest. You can check the foreign exchange rate specifically. The exchange rates of the above three countries 1 are different.
