Helped me appraise and sell my family’s collection of coins and jewelry over a period of several months. Got us top dollar, very patient. And that guy Adam, below, works for a competitor!

The guy may be an ANA member but not an authorized dealer with NGC, PCGS, etc. which tells you something about the guy's level of expertise. He is all over the map with his pricing and grades, many items are shoot for the moon prices others are below wholesale. He must be ripping off owners because of what he sells stuff for. Lots of hype, not very professional; plus he ripped off a friend. Get three offers from leading dealers before selling.

A real pro, knows coins and estates inside and out. Made best offer of anyone in region. And, unlike his competition (Steph H, below) he plays fair!

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 didn't charge a cent! --Elaine, Peeksille, NY



He's a straight shooter! I returned to him after visiting two other dealers. His offer was the best. --Gary, Riverdale, NY



My Uncle spent so much time assembling his collection, he wouldn't have wanted a single dime melted. Marc found a home for every piece. --Gail, Stamford, CT



HVN helped us with a difficult estate. There were five of us and were arguing about jewelry and silver and gold, and he cut through the nonsense and helped us each get our share. --Karen, Ft. Lee, NJ



They educate you before making an offer. I'd been stalling for so long, I wish I hadn't waited. --Marilyn, East Side, Manhattan
