Preserve the Value of Your Collection

Never attempt to clean anything yourself. Leave this to the professionals—some items become worthless in the process.

Keep items in original condition and holders. The less you touch them, the better. Handling typically lessens an item's value.

Don't handle anything directly, wear thin gloves. If you must handle a coin, wash your hands and hold it by the edges.

Marc Rosner Portrait

Marc Rosner  "a numismatist first, a dealer second"

If I don't know about something and you need help with it, I make it my business to let you know, and to find out what we need to know to do the job right. I hold a B.A. in Historical Archaeology from Wesleyan University, and an M.A. in Science Education from Columbia University. I have over 30 years of experience collecting and dealing in rare items, and enjoy meeting people and hearing stories about the things that they have. I publish and write articles and books on science and numismatic education. [read more]

Hear It From Our Clients!

  • "Thank you Marc. It was nice meeting you today. I knew from your first text that you were a man of integrity and would steer me in the right direction regarding these coins. My dad passed in 1989 and the coins sat, as you saw them, since way before then. So it was time to do something. I'm glad they will be enjoyed by someone. Thank you again. And I will definitely recommend you."

    • Joan
    • South Salem, NY
  • "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."

    • Elaine
    • Peekskill, NY
  • "Marc's a straight shooter! I returned to him after visiting two other dealers. His offer was best from the start."

    • Gary
    • Riverdale, NY
  • "My uncle spent so much time assembling his coin collection, he would roll over if a single dime were melted! Marc found a home for every piece."

    • Gail
    • Stamford, CT
  • "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."

    • Julian
    • Ft. Lee, NY
  • "They educate you before making an offer. I'd been procrastinating for so long, I wish I had called sooner."
