Collector notes
Visiting a coin shop
A few notes before you walk into National Coin & Stamp Co in Tyndall, 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.
Stay with your coins
Do not leave a box on the counter and wander the cases. Do not ask the dealer to watch your bag while you go to the car. Your lot stays in front of you until the deal is done or you pack up. That is how both sides stay comfortable.
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.
Not every coin shop is a pawn shop
Some do jewelry and scrap. Some do not. Ask if you have gold jewelry, a watch, or diamonds. Do not assume, and do not be put out if coins are what they do. The right shop for coins may send you next door for the rest.
Bring the holders, papers, and boxes they came in
Original packaging, certificates, and grading-company holders matter. Do not dump everything into a bag to “make it easier.” The dealer would rather see it the way it has been kept. Leave coins in PCGS, NGC, or ANACS holders.
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.
