Dear Michael,

That's like asking a dentist the safe way to fill your own cavity. Odds are an untrained person will do irreversible damage. If the "green" corrosion is very light it may be salvageable. If it's a valuable piece I offer conservation services that may be worth it. To illustrate: I was doing an appraisal for a lawyer in Bro...

Dear Arnold, 

Here is my honest opinion, borne out of experience. As much as I love coins and bullion, I would not advise you to "stack" silver or other precious metals for a number of reasons.

My mother found diamonds in my grandmother's condo, they were inside a shirt that was sealed in the original Macy's package like new. I can als...

Q. Is it true that if you clean your old coin it loses its value?

The short answer is yes. Unless you are trained to do it, cleaning a coin will remove the oxidation, or "toning," and render it much lower in value. Once that's done, trying to fix it will only make things worse. A qualified numismatist may know how to clean off dirt and grease and restore a coin to its original beauty; but like a fine piece of ...
