Collector notes
Visiting a coin shop
A few notes before you walk into The Diamond Ring Company in Hayward, CA. 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.
Follow the house rules without a debate
Bags on the floor, backpacks zipped, one person at the glass — shops set these for a reason. Argue about it and the visit is already off. If a rule is unclear, ask. If it is clear, do it.
Say thank you even if you do not deal
Looking is part of the hobby. Buying or selling is not required. If they spent time with you, say thanks and mean it. A short good visit is how regulars are made. A review later, if you had a fair experience, helps the shop more than a vague promise to “come back sometime.”
Keep paper money flat and in sleeves if you have them
Do not fold old notes to “fit the envelope.” Do not rubber-band a stack of large-size bills. Do not tape tears. Bring them as they are. Currency people would rather see an honest wrinkle than a new crease you added in the car.
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.
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.
