Collector notes
Visiting a coin shop
A few notes before you walk into The Gold Mine, Inc. 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.
A hold is a promise. Mean it.
If they hold a coin for you, ask how long and how you pay. Come back or call. Do not park the same piece at two shops. Dealers remember the customer who used a hold as a free option. They also remember the one who did what they said.
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.
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.
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.
Check hours before you drive
Listings show hours when the shop has shared them. They still change for lunch, shows, and appointments. If you are coming from across town, call or look at the hours on this page. A two-minute check beats a locked door.
