Pocket knives, 3/8" drive ratchet, numerous sockets, 2 or 3 combination wrenches, 100 foot tape measure, Bose QuietComfort 15 noise cancelling headphones (in almost new condition), numerous hats, shirts, a couple of sweatshirts, a Pearl Izumi windbreaker, a 1/2" drive breaker bar, a truck tire gauge (big one goes up to 120 PSI), probably at least half a dozen screwdrivers including a nice CAT rated electrician's screwdriver (I think they're around $30). A roll of blue tape that I'm still working on finishing (I use it as a print surface on my 3D printer). At least a couple of pair of pliers.
2 wallets, handed over to the police station. Never any loose money.
I'm sure a bunch of other stuff. At least once a week I see something in a toolbox or on a shelf and think "I don't remember buying that" and then think "Oh right, I found that in the road about 5 years ago.
I've pulled probably hundreds of nails and screws out of the road too, trying to save people's tires. I just picked up about 50 sharp finish screws out of the road last night.
