Collector notes
Visiting a coin shop
A few notes before you walk into The Diamond Ring Company in Hayward, CA. 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.
Regulars get easier visits because they are known
Introduce yourself. Come back. Pay as you said you would. The second visit is almost always smoother than the first. A local shop is a relationship, not a vending machine. That works in your favor when you have something unusual.
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.
Decide how you want to be paid before the offer
If you are selling, know whether you need cash today, a check, or time to think. Changing the method after they have made a number can change the number. A clear “I would like a check if we agree” at the start saves a second conversation.
Bring identification on a larger visit
A license in the car does not help at the counter. If you might sell, buy something expensive, or move cash, bring ID in with you. It speeds things up and avoids an awkward pause after you already agreed.
