Q. Included in a modest coin collection I inherited is an uncirculated silver dollar that has a bronze like patina, which I'm told is OK. However, there is also a bit of green. Should that be removed? How may I safely do so? thank you -- Mike B.

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 Bronxville who purchased a commercial coin product over the Internet to clean an uncirculated 1884-S Morgan Dollar, which had a value of $7,000. His efforts remov...

Q. Hello. I am a newly retired health care professional. I am looking for help in planning an inheritance for my five grandchildren. Is silver "stacking" a good option?

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. Silver and gold are not great long term investments, unless you happen to time things right. They don't go perpetually up, they wander with the economy, peak once a generation, and drift back down. They don't pay a dividend, you can't eat them, and there is plenty in the Earth's crust and in private an...

Q. Marc. Thank you for the advise. I would like to work with you. I am considering buying full set of silver American Eagles; 32 coin/oz. Found a circulated set on-line for less than $700. Your opinion please.

Buy it if it makes you happy!

Q. Marc. Thank you for the advise. I would like to work with you. I am considering buying full set of silver American Eagles; 32 coin/oz. Found a circulated set on-line for less than $700. Your opinion please.

These are worth their weight in silver, about $17.50 per ounce today. I advise you buy it to enjoy it, not as an investment.

Q. I am interested in the currency used in the Hudson Valley between 1650 and 1850- What you have available- and there are good books to read you recommend. I had an ancestor in Saugerties NY in 1687- am studying what currency they used then for trade. Thanks

I usually keep such notes for my own collection. I have a nice Ballston Spa note for $250, small size; and some more common ones from New York City. You should read about obsolete currency, and check out the auction archives of Heritage Currency for local banks.

Q. We're cleaning out my mom's house and finding more and more stuff. Do you help with "hoarding" situations?

Eughan, your situation is more common than you may realize and one of our specialties. Check EVERYWHERE, every file folder could contain currency, the attic floorboards could be covering silver and gold. 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 also come do a site visit and help you search. I have a metal detector to boot, one of my clients had several jars buried in the yard, each with a hundred o...

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 art, that coin must be handled skillfully.

Q. I’m just wondering I have so many old coins I can’t upload them all is there an other way to do this

Of course! Call me at 914-649-3317 I can figure out all sorts of things with you over the phone. --Marc

Q. Hi Marc, My father gave me his Roman coin collection and I was wondering what the best way is to handle it. I am fairly new to the coin collecting genre and would love some advice! Thanks! Chip

First, don't clean anything. Keep the coins stored in a cool, dark, dry place. We can do an appraisal when you're ready! Marc

Q. I have silver libertys I would like to liquidate, can I bring them all with me, and conclude an exchange at that time/rate with a payment
