Home renovations can be tiresome and time-consuming, not to mention expensive. But for some fortunate homeowners, they ended up being treasure troves! From one-of-a-kind artwork, to cold hard cash, we’ll show you some of the most expensive items ever found during home renovations.

There’s also the plumber who found a solid gold brick while taking apart a bathroom for his client-who was sorely missing his gold bar that he’d somehow misplaced!
