“At first I thought my eyes were deceiving me,” Mattsson said to the local Piteå Tidningen after the discovery.
Instead of the usual “Carl XVI Gustaf Sveriges Konung” ('Carl XVI Gustaf Sweden’s King'), the text written around the image of the King's head on Mattson's coin read “Vår horkarl till Kung”, which translates roughly into English as “Our man whore King”.
Meanwhile, Mårten Gomer, technical expert of notes and coins at the Riksbanken, is also surprised at the news.
“We’ve never come across this before. It’s really rare that you find counterfeit coins in Sweden,” he told the paper.
“My immediate impression is that it’s from a normal one krona coin. Someone has put a lot of time into it, and it was incredibly well done.”
The find has also left local police scratching their heads.
“I’ve never heard of something like this happening,” said Lars-Göran Johanssonof the Piteå police to the paper, adding that it’s become more unusual to see counterfeit money.
The one krona coin is worth $0.14 and is the smallest denomination in the Swedish currency.
That seems to be a hell of a lot of work for that little 'joke'...
