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.
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.
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.
A real look takes more than thirty seconds
Dates, mint marks, damage, weight, and whether something is collectible or melt all take time. Do not rush a careful dealer. Do not dump two hundred coins and ask for a number while you check email. Stay with the lot. Answer questions.
Call ahead with a large collection or an estate
A suitcase is not a walk-in impulse. Tell them roughly what you have and when you can come. They may want a second set of hands or a block of time. That is how you get a fair look instead of a glance between other customers.
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.
