Don't Clean Anything
Never attempt to clean items yourself. Even gentle cleaning can destroy numismatic value. Leave it to the professionals.
Keep Original Holders
Keep items in their original condition and holders. The less you touch them, the better — handling diminishes value.
Handle With Care
If you must handle items, wash your hands, wear thin cotton gloves, and hold by the edges only.

What Our Clients Say
“
I didn't know anything about the coins and currency my father left me. Marc spent two hours with me, authenticated them, explained their value, and told me all my options.
“
Marc's a straight shooter! I returned to him after visiting two other dealers. His offer was best from the start.
“
HVN helped us with a difficult estate. Five siblings argued for weeks about jewelry and antiques, then we met him and he cut through the nonsense in one evening and got each of us our share.
“
They educate you before making an offer. I'd been procrastinating for so long, I wish I had called sooner.
“
My uncle spent so much time assembling his collection. Marc found a home for every piece. He would have approved.
“
Marc is knowledgeable, fair, and truly trustworthy. I felt completely at ease the entire time.
“
I came in expecting a lowball offer like I'd gotten elsewhere. Marc gave me a thorough explanation and a fair price. I left satisfied.
“
I knew from your first text that you were a man of integrity. My dad passed in 1989 and the coins sat since then — it was time to do something. I'm glad they found a home.
