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.
Bullion and collector coins are different conversations
Melt moves with the market. A key date does not. Say what you think you have, then let them look. Mixing “it’s old so it must be rare” with a junk-silver bag slows everyone down. Sort in your mind: weight versus date.
One extra person is fine. A committee is not.
A spouse or a sibling who must agree is welcome. A table of relatives debating every coin is not a shop visit. Pick the decision-makers. Leave the rest home or in the car. The dealer can talk to two people. They cannot run a family meeting.
Cash is still common. That is normal.
Coin and bullion shops have worked in cash for a long time. It is not shady by itself. Count together at the counter. Do not count a stack in the parking lot with the door open. If you are uncomfortable carrying cash, say so and ask what else they can do.
Never step behind the counter
That side of the glass is staff only — even if you “just want to show them something in better light.” Hand the coins across. Wait to be invited if they have a viewing area. Crossing the rail uninvited is how visits end early.
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.
