I think I read something on an older post, but cant seem to find it. I bought an ultrasound machine yesterday because I like "experimenting" with coins and there apperance. I wanted to see what ultrasound does to coins that have organic componds on them as well as heavily toned coins. I would try not just using water, but a mixture if things. Water being the base, maybe adding a drop here or there of ez est, amonia etc. I wanted to see if I could "restore" a 1882 proof 65 Trade dollar I have thats toned. Maybe re submit and get a cameo grade as well. Im just kidding. I use walking lib halves, morgans, peace etc. usually I find ones that look like they could be sometging special if there wasnt so much stuff on them. Anyone ever try ultrasound? Thoughts and opinions welcome. |

A big, water filled ultrasound machine like the one used at hospitals to clean instruments

I use one of those to clean any of my harmonicas without wooden reeds. You had me going at the beginning of this post!  If you clip them into place when the coin vibrates it would case hairline scratches. Is their a way to suspend the coin in the liquid without holding it in place? |

Are your coins expecting? Seriously, this sounds like a really bad idea. The #1 rule of numismatics:
Don't clean coins.

An Ultrasound is different then what you are doing.

We use an ultrasonic cleaner in my line of work, it uses high frequency vibrations to remove loose debris and other junk from our instruments prior to sterilization. I don't think it will have an effect on toning. As a matter of fact, if your coins are next to one another or on the bottom of the cleaner, it might cause them to rub together and get scratches. Just my 2c!

Yeah I'm not sure if I would put more than one in at a time. I kinda figured if they touched it could damage them. I know what everyone says about cleaning coins. I'm not using high dollar coins here. Most have prob been cleaned at one time. Some coins are just ugly. Besides being handled millions of times, some look as though they have been stained with god knows what. My favorite is the green stuff on some. Ultrasound is vibration through water, not scrub brushes. I dont think it would do any damage to a coin if used properly. Anyone know if water hurts silver coins? I will eventually use a perfectly fine morgan to see what ultrasound does to the luster. If it would change its appearance as a chemical dip would.

The biggest concern with ultrasonic cleaning is vibration of the coin against metal parts of the bath. It should be ok as long as you have only have one coin at a time in a plastic/rubberized basket or some sort of suspension device.

There is a rubber mat inside. I plan on experimenting this weekend.

IF the coins used are in already rotten shape, not much to loose by experimenting. However, always remember a cleaned coin is just not worth as much.
