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.
Count money together, then put it away
Whether you are paying or getting paid, count at the counter where both of you can see. Then put it away. That protects you and the shop. If something is off, it is much easier to fix before anyone has left the glass.
Kids are welcome when they stay with you
Most shops like young collectors. Keep children next to you, not behind the counter or in the cases. Hands off other people’s coins. A short visit with one or two questions beats a long visit where the dealer is watching the room instead of helping you.
They do not have to buy what you brought
A shop can pass on tokens, damaged coins, or a category they do not handle. “We don’t buy that” is information. Ask who might. Do not argue them into a box they cannot use. A clean no today keeps the door open next time.
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.
