Had a quick search and didn’t see a topic for this.
Found a few things on the road of late. A screw driver, a few d shackles with and without the pin. Today a Kendo brand of shifter. Did a U turn for that one. Never heard of “Kendo” as a brand name, but it seems good. Into the tool box with it.
As others may attest, the bulk of what i find is cassshhhhhhh. #guttercashking
(sadly i find far less than i used to thanks to the ol cashless economy) 
Funny this thread popped up today. On my ride this afternoon I came to the conclusion I was probably following a tradie that had not secured their tool bag or similar as i was seeing spanners and screwdrivers quite frequently along one stretch. Nothing that looked good enough for stopping for, especially as it would have had to go into a lycra jersey pocket and probably wear a hole by the time I got home.
I found a great reusable Woolworths shopping bag on the last ride. Washed it up and it’s in rotation already.
In the past I have found:
A complete set of Chinese metric spanners 7-25mm in the tool rool
Two flat bladed screwdrivers
A set of 12 coloured pencils
2 Campagnolo chainring outer bolts (no inners)
A Hazardous Material sign that literally fell off the back of a truck
Never found any money. Or a 10mm socket.
