Collector notes
Visiting a coin shop
A few notes before you walk into The Diamond Ring Company in Hayward, 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.
Insurance and probate need different paperwork
If a lawyer, an executor, or an insurer sent you, say so. Bring what papers you have. The shop may not be the appraiser you need, and they will tell you. That honesty is useful. It is better than leaving with the wrong kind of number.
Buying a specific date? Call first.
Shops cannot stock every date and mint. A one-minute call — or a want list — saves a trip. If they have it, they can pull it. If they do not, they can watch for it. Walking in cold for one coin is a hope, not a plan.
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.
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.
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.
