Two weeks ago I found a Klein Tools electrician's screwdriver. It was dirty but cleaned up perfectly. They're worth about $20 new. I've probably found $50 or $60 in tools over the years.
The only "money" I pick up is beer cans. Some people who drive my route must like really crappy beer, because almost every day I could probably pick up a couple of Bud Lite cans.
The only real money I've ever found was still in the wallet with ID, so it just got taken to the police dept.
