Collector notes
Visiting a coin shop
A few notes before you walk into Quinnipiac Gold & Diamond Exchange in North Haven, CT. 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.
Say thank you even if you do not deal
Looking is part of the hobby. Buying or selling is not required. If they spent time with you, say thanks and mean it. A short good visit is how regulars are made. A review later, if you had a fair experience, helps the shop more than a vague promise to “come back sometime.”
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.
Saturday morning is often the busy window
That is when collections walk in and regulars stop by. Fine if you like energy. Less fine if you want a long, quiet look at an estate. Midweek late morning is often easier. If you need time, ask when they are slower.
Do not crack a graded holder in the shop
PCGS, NGC, ANACS, and CAC holders are part of the product. Opening one at the counter to “see it better” can wreck the value. If you want it out, that is a decision you make at home, not a demonstration.
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.
