Collector notes
Visiting a coin shop
A few notes before you walk into Grandpas coins in Vallejo, 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.
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.
When metals jump, the shop gets busier
A sharp day in gold or silver fills the parking lot. Offers take longer. Lines get real. If you can wait a quieter day, you will get a better conversation. If you cannot, bring patience and a simple list of what you have.
A buy offer is not an appraisal
An offer is what this shop will pay today. An appraisal is a written opinion, often for insurance or an estate, and it is a different service. If you need a document, say that first. Do not treat a verbal number as a formal appraisal.
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.
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.
