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.
Do not walk in at closing with a suitcase
Five minutes to close is time to pick up a hold, not to dump an estate. Large lots take time to weigh, look up, and talk through. Call earlier in the day and ask when they can give you a proper look. A shop that is locking the door still has to balance the register and get home.
What happens at the counter is private
Do not repeat another customer’s name, address, or what they sold. Do not film the register. Shops are small towns. Discretion is part of being a decent visitor. It is also how you get treated like one.
Lunch and after-work can stack the counter
Local shops get a rush when people are off the clock. If you have a box, those windows are the wrong time to expect a leisurely offer. Call and ask when they can sit with it. Most dealers would rather schedule you than rush you.
Tell them if a coin is damaged, cleaned, or already graded
Hiding a problem wastes time and trust. “This one was cleaned” or “this already came back from PCGS” is useful. Dealers would rather adjust than feel tricked. Honesty on the small things makes the rest of the visit easier.
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.
