Dealer location
Street is not on file. The pin is the ZIP or city area — not a door.
Collector notes
Visiting a coin shop
A few notes before you walk into Treasure Island Coins 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.
Be present when it is your turn
Take the call outside. Pull the earbuds. The dealer is about to look at your coins or pull something you asked for. A face-to-face minute is worth more than a half-distracted twenty. If you need to text a spouse about a number, say so and step aside.
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.
Saturday morning is often the busy window
That is when collections walk in and regulars stop by. Fine if you like energy. Less fine if you want a long, quiet look at an estate. Midweek late morning is often easier. If you need time, ask when they are slower.
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.
