Here's what I learned from you Richard ....and this is a FACT.

The FACT is that you said, "i did not say you should clean a gold coin that is 150 years old in the cleaner, im talking about silver strikes...,"

Here's a reasonable question for you ...
Why is a silver strike acceptable ... but a 150 year-old gold coin is not .... if your machine is so effective and not harmful? Can you answer my question factually without going on the defensive?
