Collector notes
Visiting a coin shop
A few notes before you walk into Treasure Island Coins in ND. 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.
Never step behind the counter
That side of the glass is staff only — even if you “just want to show them something in better light.” Hand the coins across. Wait to be invited if they have a viewing area. Crossing the rail uninvited is how visits end early.
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.
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.
“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.
Cash is still common. That is normal.
Coin and bullion shops have worked in cash for a long time. It is not shady by itself. Count together at the counter. Do not count a stack in the parking lot with the door open. If you are uncomfortable carrying cash, say so and ask what else they can do.
