Many of these coins I inherited are dirty. I have a steam cleaner and ultrasonic cleaner I use in my dental lab. I am aware of the no cleaning rule but how it applies to these methods?

Thanks

to the CCF!

I've read that ultrasonic cleaning can cause microscopic scratches on the surface of the coins. The dislodged debris from the coin or the plastic basket can rub against the vibrating coin and damage it. I can't really find anything on steam cleaning causing damage, but if it's a pressure cleaning device, I would think the same would apply to the dislodged material moving across the surfaces, but that's just my opinion.

I would tend to agree with that.

Ultrasonic cleaning is very often used by professional jewelers for pieces valued at $thousands.

Haven't tried pure boiling water, but most of know about acetone.

I don't see enough difference in the before and after images to justify the process. Also, the steamed coins seem to have a blueish tone to them that doesn't look natural. I would prefer the original dark coins over the steam treated coins because, to me, the steam makes them looked cleaned.

Just Carl, yes I know what Acetone is but dont have any in my lab.
Yokozuna, I would agree with this. It 'looks' cleaned in my hand too. But doesn't look blue in my hand so thats lighting or flash.

Thanks
Rex
