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.
Lunch and after-work can stack the counter
Local shops get a rush when people are off the clock. If you have a box, those windows are the wrong time to expect a leisurely offer. Call and ask when they can sit with it. Most dealers would rather schedule you than rush you.
Keep quiet about another customer’s coins
Do not grade, joke about, or value coins that are not yours. “That’s only a VF” from behind someone who is selling grandpa’s album is not helpful. Look at the cases. Let the dealer run their counter. You will get your turn.
Stay with your coins
Do not leave a box on the counter and wander the cases. Do not ask the dealer to watch your bag while you go to the car. Your lot stays in front of you until the deal is done or you pack up. That is how both sides stay comfortable.
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.
Know roughly what you brought
You do not need to be an expert. A simple list — silver dollars, a few proofs, a bag of wheat cents — helps. “I have no idea, you tell me” on a mixed box is fine once. It is harder when the box is huge and you cannot say what you want out of the visit.
