I have found change , casually enough that I pay no attention, But once I found a quart size Chinese container full of change ,
pennies naturally but plenty of quarters dimes nickels
A better find times 2
was a belt buckle that had a Morgan silver dollar insert not a key date but a silver dollar
then a nick knack container with 2 half 90% silver dollars
I've also found as much as 5 grams of gold over the years (careless people )
but when I had theft years ago they found it .
