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 real look takes more than thirty seconds
Dates, mint marks, damage, weight, and whether something is collectible or melt all take time. Do not rush a careful dealer. Do not dump two hundred coins and ask for a number while you check email. Stay with the lot. Answer questions.
They may weigh, look up, or photograph
That is how a careful shop works. It is not stalling. Stay with your coins. If they need a minute in the back, that is their process. Ask if you are unsure what is happening. Curiosity is fine. Suspicion as a default is not.
Show week can empty the shop — or pack it
If the dealer is on the road, the store may be closed or on shorter hours. If they just got back, they may be unpacking. Check this listing for upcoming shows and call if your visit is important. It is not personal. The bourse is part of the business.
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.
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.
