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.
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.
Large cash deals may require identification
That is federal law on certain cash amounts, not the shop being nosy. Bring a government ID if you plan to move a lot of cash either direction. A dealer who asks for ID on a large deal is doing the job the right way.
Say thank you even if you do not deal
Looking is part of the hobby. Buying or selling is not required. If they spent time with you, say thanks and mean it. A short good visit is how regulars are made. A review later, if you had a fair experience, helps the shop more than a vague promise to “come back sometime.”
Follow the house rules without a debate
Bags on the floor, backpacks zipped, one person at the glass — shops set these for a reason. Argue about it and the visit is already off. If a rule is unclear, ask. If it is clear, do it.
Bullion and collector coins are different conversations
Melt moves with the market. A key date does not. Say what you think you have, then let them look. Mixing “it’s old so it must be rare” with a junk-silver bag slows everyone down. Sort in your mind: weight versus date.
