Our last pro-bono event was the WHUD Spring Kids' Fair at S.U.N.Y. Purchase College, where we taught hundreds of children about coins and currency, and gave out more than $1,500 in numismatic material as gift-in-kind donations. Proceeds supported the H.O.P.E. for Youth Foundation.

Our upcoming shows include Westchester, Danbury, Naugatuck, and Hartford/Cromwell. We always welcome new material to sell!

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 Br...

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 wit...

Silver, as an investment, wanders in value. Buy it if it makes you happy.

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.

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.

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 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 ...

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

They are all steel. Some may look like they are a different metal because of oxidation. We buy these for 1.5 cents apiece, and sell them for 2 cents. We can pay more for a large number, such as ten or more rolls ($5 face value).

Q. Do you appraise stamps? Do you buy stamps?

Asked by Jordan Ellsworth on May 26, 2018

Q. Hi, is it true that a single 1943 penny is worth many thousands of dollars?...

This is possibly the most common question we get asked. Your 1943 cent (Britain has pennies, not us!) is worth a cent. The confusion arises from the fact that these cents were made out of zinc-coated steel. While there are a few copper 1943 cents (and a few steel 1944's) out there, I'm confident you don't have one. You'll know because you can li...

This depends on the grade and mint Mark, I have to see them. Also a full sovereign and a half sovereign they look exactly the same and so it should be weighed or measured. An uncirculated Australia sovereign of that date can retail for &400. A worn common one scraps at $250. That's your range. It was made as a bullion product and i...

Asked by Andres on May 26, 2018

Q. Is my 1878 Morgan Silver Dollar worth $5,000?

Odds are it's worth $15-20. The U.S. government made millions more silver dollars than were ever needed because of a powerful silver lobby. Hundreds of thousands have been found in modern times in uncirculated bank bags. Your early dollar may look great, but the dies were sharp back then and many people set them aside. It's harder to find a dime...

Asked by Alyssa on May 26, 2018

Q. I found a jar of old coins. Which are silver?

All dimes, quarters, half dollars, and dollars minted 1964 and earlier. Many were set aside from circulation around that time, and as of today (March 13, 2018) they are worth about twelve times face value. So a dime is worth $1.20 in silver.
