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.
Do not ask them to come out to the car
Bring the coins inside. A dealer should not leave the store to look at a trunk. It is a safety issue for them and for you. If the lot is heavy, make two trips or ask if they have a cart. The work happens at the counter.
What is in the case today may be gone tomorrow
Coin shops turn inventory. A picture from last month is not a hold. If you want a date or a grade, call or start a want list. Showing up and hoping the exact piece is still there is how people get disappointed.
Cash is still common. That is normal.
Coin and bullion shops have worked in cash for a long time. It is not shady by itself. Count together at the counter. Do not count a stack in the parking lot with the door open. If you are uncomfortable carrying cash, say so and ask what else they can do.
Shopping an offer is etiquette when you are honest
“I want to hear one more shop, then I will decide” is adult. “I already promised it to you” when you have not is not. If you come back, say what changed. Dealers respect a straight process. They do not respect being used as a foil.
Buying a specific date? Call first.
Shops cannot stock every date and mint. A one-minute call — or a want list — saves a trip. If they have it, they can pull it. If they do not, they can watch for it. Walking in cold for one coin is a hope, not a plan.
