I suppose that depends on what you are doing with them. The clad I find ends up going to Coinstar after a basic rinse and my container fills up. It accepts most of them, unless the sides have started to corrode away. For the coins I am keeping, I usually do an acetone dip or olive oil soak, unless is happens to be a valuable date, which has not happened for me yet. I'll cross that bridge when I get to it.
Thanks, I like the vote of encouragement! Although the mounds of snow and frozen ground here in Michigan will likely dictate how soon the hunt can begin.
SH suggestion is a good one and I might add, when tumbling, separate the pennies from the other clad as they will turn your other coins copper color! A twin tub tumbler from Harbor Freight is about 50.00!
HH!
