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.
Know roughly what you brought
You do not need to be an expert. A simple list — silver dollars, a few proofs, a bag of wheat cents — helps. “I have no idea, you tell me” on a mixed box is fine once. It is harder when the box is huge and you cannot say what you want out of the visit.
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.
Stay with your coins
Do not leave a box on the counter and wander the cases. Do not ask the dealer to watch your bag while you go to the car. Your lot stays in front of you until the deal is done or you pack up. That is how both sides stay comfortable.
Give the counter some room
Lean on the glass, hover over an open box, or park six relatives at the rail and nobody can work. Leave space for the dealer to move trays, use a loop, and talk privately. Extra people can wait in the shop or the car unless they are needed to decide.
This is a working shop, not a museum desk
They will talk coins. They will not give a free seminar on forty pieces while a line forms. Pick your best questions. Buy a book if you want to learn the series. A dealer who teaches a little is being generous with the clock.
