<p>[QUOTE=&quot;rhoggman, post: 390722, member: 13987&quot;]Ultrasonic jewelry cleaners use sound to vibrate the object at a high frequency. It is supposed to shake dirt free, but they also use a detergent solution. I would think this would work if the coin was on a soft surface that would not be damaging to the coin. But really you never know whether the surface of the coin would be affected because of what the coin would be touching while it was vibrated?????[/QUOTE]</p><p><br /></p>
