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 Cornerstone Bullion in CO. 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.
Cameras and a locked door are normal
Buzz-in doors, counters, and cameras protect the shop and the people in it. They are not aimed at you personally. Follow the house rules. If you are asked to wait to be let in, wait. That is a well-run store, not a cold shoulder.
Kids are welcome when they stay with you
Most shops like young collectors. Keep children next to you, not behind the counter or in the cases. Hands off other people’s coins. A short visit with one or two questions beats a long visit where the dealer is watching the room instead of helping you.
Decide how you want to be paid before the offer
If you are selling, know whether you need cash today, a check, or time to think. Changing the method after they have made a number can change the number. A clear “I would like a check if we agree” at the start saves a second conversation.
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 ask them to come out to the car
Bring the coins inside. A dealer should not leave the store to look at a trunk. It is a safety issue for them and for you. If the lot is heavy, make two trips or ask if they have a cart. The work happens at the counter.
