Collector notes
Visiting a coin shop
A few notes before you walk into Treasure Island Coins in Sioux Falls, SD. 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.
Large cash deals may require identification
That is federal law on certain cash amounts, not the shop being nosy. Bring a government ID if you plan to move a lot of cash either direction. A dealer who asks for ID on a large deal is doing the job the right way.
If you feel rushed, you can pause
You are allowed to say you need a minute. You are allowed to pack up and think. You are not required to decide while someone is waiting behind you — step aside and let them go. A good shop would rather you be sure than sorry.
Decide if you are selling all of it or part of it
“I need this gone” and “I only want to sell the silver” lead to different offers. Decide before you sit down. Changing the goal halfway through wastes their time and yours. It is fine to keep a piece that is sentimental. Say which one.
Not every coin shop is a pawn shop
Some do jewelry and scrap. Some do not. Ask if you have gold jewelry, a watch, or diamonds. Do not assume, and do not be put out if coins are what they do. The right shop for coins may send you next door for the rest.
“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.
