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.
Follow the house rules without a debate
Bags on the floor, backpacks zipped, one person at the glass — shops set these for a reason. Argue about it and the visit is already off. If a rule is unclear, ask. If it is clear, do it.
Ask how this shop likes to pay and get paid
Cash, debit, credit, check, and wire are not universal. Some counters are cash-friendly on bullion. Some run cards every day. Some write a check on a larger buy. Ask before you assume. Have a backup so a good deal does not stall over the last step.
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.
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.
Be present when it is your turn
Take the call outside. Pull the earbuds. The dealer is about to look at your coins or pull something you asked for. A face-to-face minute is worth more than a half-distracted twenty. If you need to text a spouse about a number, say so and step aside.
