My weapon of choice is the Hammer...Sometime you can peal them when they are first dug and still wet. I try and scrap them on my scoop or sifter. Most are to tuff, pennies trash.. nickels, they do fairly well except war nickels.. I trash most of those, to bad to waste time.
All silver gets the hammer and then into the melt pile. Clad quarters, I tumble and use those as change.
As you can see the coins are a mess.
