Collector notes
Visiting a coin shop
A few notes before you walk into American Diamond Exchange, Inc. in New Haven, CT. 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.
Ask before you touch anything in the case
The dealer will hand you a coin or put it on a pad. Do not reach into a tray or slide a slab toward yourself. Handle coins by the edges if they are raw. If you drop something, say so immediately.
If you are getting another offer, say so up front
On a large lot it is fair to hear more than one shop. Tell them. A good dealer would rather know than spend an hour and find out you were only using them for a number. Do not treat a courtesy look as free inventory research for the next counter the same afternoon.
Bring the holders, papers, and boxes they came in
Original packaging, certificates, and grading-company holders matter. Do not dump everything into a bag to “make it easier.” The dealer would rather see it the way it has been kept. Leave coins in PCGS, NGC, or ANACS holders.
Count money together, then put it away
Whether you are paying or getting paid, count at the counter where both of you can see. Then put it away. That protects you and the shop. If something is off, it is much easier to fix before anyone has left the glass.
Follow the house rules without a debate
Bags on the floor, backpacks zipped, one person at the glass — shops set these for a reason. Argue about it and the visit is already off. If a rule is unclear, ask. If it is clear, do it.
