It seems like about the only time you might score is when some kid steals them out of dad's coin collection and buys some candy or whatever ... at face value. I searched through a lot of change as a kid in the late '60s and '70s. Not much since.
The last coin of numismatic value that I found was a steel nickel about 5 years ago.
I had a silver quarter given to me in change about a year ago. I assume the kids not knowing what older coins were passed that on to me.
How worn was the coin? Most of the silver I found years ago was well worn, poor to fair condition. I had a stack of buffalo nickles sorted from the rest that you couldn't even read the dates. It would be a wonderful day to find silver that was in very good to fine condition in circulation.
It was fully in the "junk silver" category.
