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.
They may weigh, look up, or photograph
That is how a careful shop works. It is not stalling. Stay with your coins. If they need a minute in the back, that is their process. Ask if you are unsure what is happening. Curiosity is fine. Suspicion as a default is not.
Online asking prices are not what a shop pays
A listing, a completed auction before fees, and a dealer buy price are three different numbers. Screenshots of asks are not a bid. Bring the coins. Let them look. Then talk. You will get further than arguing from a tab on your phone.
Do not clean the coins
Polish, dip, baking soda, and a toothbrush lower the value of most collectible coins. Leave dirt and toning alone. If you already cleaned something, say so. A dealer would rather hear the truth than discover it under a lamp.
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.
Keep quiet about another customer’s coins
Do not grade, joke about, or value coins that are not yours. “That’s only a VF” from behind someone who is selling grandpa’s album is not helpful. Look at the cases. Let the dealer run their counter. You will get your turn.
