Collector notes
Visiting a coin shop
A few notes before you walk into Treasure State Coins in Plains, MT. 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.
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.
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.
Ask if they buy the whole lot or select pieces
Some shops write one number for the box. Some pull the coins they can use. Neither is wrong. Ask which they do before they start. If you need everything gone today, say that. If you only want to sell the silver, say that too.
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.
