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.
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.
Ask before you touch anything in the case
The dealer will hand you a coin or put it on a pad. Do not reach into a tray or slide a slab toward yourself. Handle coins by the edges if they are raw. If you drop something, say so immediately.
Check hours before you drive
Listings show hours when the shop has shared them. They still change for lunch, shows, and appointments. If you are coming from across town, call or look at the hours on this page. A two-minute check beats a locked door.
Bring identification on a larger visit
A license in the car does not help at the counter. If you might sell, buy something expensive, or move cash, bring ID in with you. It speeds things up and avoids an awkward pause after you already agreed.
Do not assume every shop takes a credit card
Many do. Some do not. Some take cards on retail and prefer another method when they are buying from you. None of that is a trick. Ask, “Do you take cards?” before you empty your wallet. If they say no, that is an answer, not a negotiation.
