Clad Coins
I tumble my nickels, dimes, and quarters for around 3 days, until all the crud is gone and they look like they have never been in the ground. I tumble them in my harbor freight duel drum tumbler along with water, and comet cleanser, and aquarium gravel. I keep one tumbler for clad, and one for copper pennies.
You can't mix copper with the clad, it will cause the clad to turn a rust color.
For my pennies, I only tumble the copper pennies 1982 and before, for about 90 minutes (hour and a half), and then roll them, along with the nickels, dimes, and quarters. I get my rolling paper from my bank. Actually, I don't roll the copper pennies, I collect them (I how have about 200 lbs) to sell for copper if this country ever quits minting pennies.
Today I dug exactly 100 memorial pennies, and 10 wheat. The wheat I save too. Oh yeah, I have a toy plastic brinks truck, with four plastic cups that when full to the line with coins, it's a full roll of coins, and easily dumps into the paper rolls and I just crimp the ends. I found the brinks truck and ordered it on line. I forgot the web site, you'll have to look around.
