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.
A written inventory helps on an estate
Even a notebook list is better than a surprise pile. Heirs who write down what they think they have get a cleaner visit. If you are the executor, bring that fact and any papers. The shop can work faster when they are not inventing the catalog with you.
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.
What happens at the counter is private
Do not repeat another customer’s name, address, or what they sold. Do not film the register. Shops are small towns. Discretion is part of being a decent visitor. It is also how you get treated like one.
Give the counter some room
Lean on the glass, hover over an open box, or park six relatives at the rail and nobody can work. Leave space for the dealer to move trays, use a loop, and talk privately. Extra people can wait in the shop or the car unless they are needed to decide.
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.
