Collector notes
Visiting a coin shop
A few notes before you walk into Sentinel Numismatics Store in Milwaukee, WI. 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.
Cash is still common. That is normal.
Coin and bullion shops have worked in cash for a long time. It is not shady by itself. Count together at the counter. Do not count a stack in the parking lot with the door open. If you are uncomfortable carrying cash, say so and ask what else they can do.
Bring the holders, papers, and boxes they came in
Original packaging, certificates, and grading-company holders matter. Do not dump everything into a bag to “make it easier.” The dealer would rather see it the way it has been kept. Leave coins in PCGS, NGC, or ANACS holders.
Regulars get easier visits because they are known
Introduce yourself. Come back. Pay as you said you would. The second visit is almost always smoother than the first. A local shop is a relationship, not a vending machine. That works in your favor when you have something unusual.
Keep quiet about another customer’s coins
Do not grade, joke about, or value coins that are not yours. “That’s only a VF” from behind someone who is selling grandpa’s album is not helpful. Look at the cases. Let the dealer run their counter. You will get your turn.
If you set a time, be on it
Some shops work by appointment on bigger lots. Be on time. Call if you are late or cannot come. The slot they held is time they did not give someone else. Reliability gets you invited back.
