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.
“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.
Do not clean the coins
Polish, dip, baking soda, and a toothbrush lower the value of most collectible coins. Leave dirt and toning alone. If you already cleaned something, say so. A dealer would rather hear the truth than discover it under a lamp.
Keep quiet about another customer’s coins
Do not grade, joke about, or value coins that are not yours. “That’s only a VF” from behind someone who is selling grandpa’s album is not helpful. Look at the cases. Let the dealer run their counter. You will get your turn.
They do not have to buy what you brought
A shop can pass on tokens, damaged coins, or a category they do not handle. “We don’t buy that” is information. Ask who might. Do not argue them into a box they cannot use. A clean no today keeps the door open next time.
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.
