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 Sisson & Son in Rohnert Park, 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.
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.
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.
Know roughly what you brought
You do not need to be an expert. A simple list — silver dollars, a few proofs, a bag of wheat cents — helps. “I have no idea, you tell me” on a mixed box is fine once. It is harder when the box is huge and you cannot say what you want out of the visit.
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.
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.
