I have found here in Colorado 11 wallets, 3 purse's, drill case with drill and accessories, money on the side of the highway, 2 boats and 1 kayak after a flood, and a bunch of other things.
One of the wallets had $ 816.00 . 2 wallets and 2 purse's had right at $ 400.00 and the rest had less than $ 200.00. And no , I didn't keep them or the money. I gave it all back. but it was fun!!!
