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.

  1. They may weigh, look up, or photograph

    That is how a careful shop works. It is not stalling. Stay with your coins. If they need a minute in the back, that is their process. Ask if you are unsure what is happening. Curiosity is fine. Suspicion as a default is not.

  2. “Best I can do” is a sentence, not an insult

    They have to sell it, hold it, and stay in business. You can say no. You can ask if they can do better on part of the lot. You should not treat a firm number as a personal slight. A calm “I need to think about that” is enough.

  3. 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.

  4. 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.

  5. Decide how you want to be paid before the offer

    If you are selling, know whether you need cash today, a check, or time to think. Changing the method after they have made a number can change the number. A clear “I would like a check if we agree” at the start saves a second conversation.
