But the 25,000 kronor (roughly $2,630) finders' fee comes 66 years after the man made the unusual discovery.
Now aged 80, he first found the sword while swimming in the river Svartån in Tranås, Jönköping, back in 1953, SVT Nyheter Jönköping reported.
But he has only just received the payment after Jönköpings Museum expressed interest in taking in the sword, which dates back as far as 1500-1100 BC.
In the summer of 2018, another ancient sword was pulled from a lake, by a Swedish-American girl who was staying at her family's summer house. That relic was dated to the years 650-770 AD, and the girl received 15,000 kronor from the state for finding the sword.
