Cleaning newer dollar coins

[Waterdog]

I often clean my coins in a rock tumbler seperating the pennies fron the clad coins. Then there are those dollar coins, where would you clean those in with the pennies or in with the clad ?

Thanks

i just toss them all in together...then, those dollar coins will sort of shine right up if they havnt been in the dirt for long with a jewelers cloth so you can spend them...the ones that dont shine up, go through the Coinstar..

I've been experimenting with the pickling method. Euro coins, 10 20 and 50 cents, came out sparkling new. I also tried a 1937 US penny. Came out as if it was struck this morning.
The results are better than using cleaners.
Tomorrow I'll try a Loonie.

Take the time and do each seperately. Now since the penny is defunct here I take less care. Never mix silver in with copper me bouy.

BE CAREFUL when cleaning the Loonie! It's plating is VERY thin.
I tried pickling a 1987 Loonie and it came out shiny and clean. The only problem was that where I brushed a bit more, the plating wore off, leaving some inner copper exposed.
