Here’s a cool thing from my buddy Claes Pettersson at JÃ¶nkÃ¶ping County Museum. He’s been directing big excavations of the town’s 17th century industrial precinct, and his team has found something that appears to be a forged gold coin. It consists of a soft grey metal (tin?) with a thin coating of a yellow metal. So far nobody’s been able to tell quite what type of coin it was supposed to look like, only that one side features a crowned head. Any ideas?
