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.
Call ahead with a large collection or an estate
A suitcase is not a walk-in impulse. Tell them roughly what you have and when you can come. They may want a second set of hands or a block of time. That is how you get a fair look instead of a glance between other customers.
What is in the case today may be gone tomorrow
Coin shops turn inventory. A picture from last month is not a hold. If you want a date or a grade, call or start a want list. Showing up and hoping the exact piece is still there is how people get disappointed.
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.
Large cash deals may require identification
That is federal law on certain cash amounts, not the shop being nosy. Bring a government ID if you plan to move a lot of cash either direction. A dealer who asks for ID on a large deal is doing the job the right way.
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.
