Collector notes
Visiting a coin shop
A few notes before you walk into Sigmund Cohn in Mount Vernon, NY. These rotate daily. They are general collector etiquette from CDXList — not this shop’s house rules. When something is unclear, ask the person at the counter.
Wait your turn at the counter
A coin shop is not a buffet line. The person already at the glass is in a private conversation. Stand back, keep your box closed, and wait to be invited forward. Jumping in with “real quick” questions while someone is selling a collection is the fastest way to start a visit on the wrong foot.
Tell them if a coin is damaged, cleaned, or already graded
Hiding a problem wastes time and trust. “This one was cleaned” or “this already came back from PCGS” is useful. Dealers would rather adjust than feel tricked. Honesty on the small things makes the rest of the visit easier.
If you set a time, be on it
Some shops work by appointment on bigger lots. Be on time. Call if you are late or cannot come. The slot they held is time they did not give someone else. Reliability gets you invited back.
Cameras and a locked door are normal
Buzz-in doors, counters, and cameras protect the shop and the people in it. They are not aimed at you personally. Follow the house rules. If you are asked to wait to be let in, wait. That is a well-run store, not a cold shoulder.
A hold is a promise. Mean it.
If they hold a coin for you, ask how long and how you pay. Come back or call. Do not park the same piece at two shops. Dealers remember the customer who used a hold as a free option. They also remember the one who did what they said.
