I think I may have tried a coin or two in the Ultrasonic cleaner when I worked at a jewelry store in the early 1990's. As I recall, it didn't do much at all.
Man, this brings back memories.........the coin shop dowtown in the early 1970"s.... and the owner dropping coins in the ultrasonice cleasner to brighten them up! Agh.....what memories........(you should see thos beauts nowadays, they need another bath!)
Craig If I had it my way, stupidity would be painful!
<< <i> Ultrasonic is vibratory. The coin must be suspended so not to allow abraiding. A water and mild soap mix could be used. >>
Exactly! I did it on dirty gold for an hour and it worked fine. One even was a $3 that went au55. Would of been a NG for sure because it was crusty,, really crusty

3000 psi Power Washer and a bench vise work good in conjunction with one another, too .... Be careful not to clamp down on the coin too hard, it could bend it
Glass bead blasting really makes it shine, too.
After that, send it in to AC- Grade™.... probably get an MS68 D CAM
I tried it on a couple ol worn out Morgans with a lot of crud in the nooks and crannies. I used distilled water and liquid dish soap. The coins came out looking like bleached, bland pathetic pieces of chit. It shud be ok but be careful to use it only on coins made from non-reactive metals like gold.

And it probably IS ok. Ok enough to get them into you know who's holders as gems.
