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.
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.
A hold is a promise. Mean it.
If they hold a coin for you, ask how long and how you pay. Come back or call. Do not park the same piece at two shops. Dealers remember the customer who used a hold as a free option. They also remember the one who did what they said.
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.
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.
