Collector notes
Visiting a coin shop
A few notes before you walk into Polylogics Consulting in Mahwah, NJ. 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.
Shopping an offer is etiquette when you are honest
“I want to hear one more shop, then I will decide” is adult. “I already promised it to you” when you have not is not. If you come back, say what changed. Dealers respect a straight process. They do not respect being used as a foil.
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.
Call ahead with a large collection or an estate
A suitcase is not a walk-in impulse. Tell them roughly what you have and when you can come. They may want a second set of hands or a block of time. That is how you get a fair look instead of a glance between other customers.
You do not have to announce what you paid
“I have three thousand in this” is not a grade or a melt value. It puts the dealer on defense and does not change what the coin is. Tell them what it is, where it came from if that matters, and what you want to do. Let the piece speak, then talk numbers.
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.
