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.
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.
If you are getting another offer, say so up front
On a large lot it is fair to hear more than one shop. Tell them. A good dealer would rather know than spend an hour and find out you were only using them for a number. Do not treat a courtesy look as free inventory research for the next counter the same afternoon.
No magnets, acids, or scratch tests on the pad
The shop has the tools if a test is needed. Do not perform experiments on the glass. You can damage the coin and the counter. If you think something is fake, say why and let them look.
Follow the house rules without a debate
Bags on the floor, backpacks zipped, one person at the glass — shops set these for a reason. Argue about it and the visit is already off. If a rule is unclear, ask. If it is clear, do it.
One conversation at a time
The dealer cannot price a collection, answer a bullion quote, and pull a date from the case at once. If they are mid-deal, wait. If you only need a quick “are you open Saturday,” say that when they glance up — then step back. Courtesy is remembered the next time you walk in.
