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.
They do not have to buy what you brought
A shop can pass on tokens, damaged coins, or a category they do not handle. “We don’t buy that” is information. Ask who might. Do not argue them into a box they cannot use. A clean no today keeps the door open next time.
Do not crack a graded holder in the shop
PCGS, NGC, ANACS, and CAC holders are part of the product. Opening one at the counter to “see it better” can wreck the value. If you want it out, that is a decision you make at home, not a demonstration.
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.
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.
Know roughly what you brought
You do not need to be an expert. A simple list — silver dollars, a few proofs, a bag of wheat cents — helps. “I have no idea, you tell me” on a mixed box is fine once. It is harder when the box is huge and you cannot say what you want out of the visit.
