Denmark and Sweden have both rejected the European Monetary Union and the euro by popular referendum. So, for the time being, there are two different currencies in the Oresund Region. 

The Danish currency is the krone (DKK), which is divided into 100 øre. 

25 øre, 50 øre (both copper)
1 krone, 2 kroner, 5 kroner (silver, each with a hole in the centre)
10 and 20 kroner (both brass) 

DKK 50, DKK 100, DKK 200, DKK 500 and DKK 1,000 

The Swedish currency is the krona (SEK), which is divided into 100 öre. 

50 öre, 1 krona, 5 kronar, 10 kronar 

SEK 20, SEK 50, SEK 100, SEK 500 and SEK 1,000

The Danish krone is roughly 25 percent higher than the Swedish krona: DKK 100 = SEK 80 / SEK 100 = DKK 124 (March 2004 rates). 

USD 100 = SEK 745
EUR 100 = SEK 920
GBP 100 = SEK 1,375 

USD 100 = DKK 600
EUR 100 = DKK 745
GBP 100 = DKK 1,112
