Collector notes
Visiting a coin shop
A few notes before you walk into Polylogics Consulting in Mahwah, NJ. 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.
What happens at the counter is private
Do not repeat another customer’s name, address, or what they sold. Do not film the register. Shops are small towns. Discretion is part of being a decent visitor. It is also how you get treated like one.
Give the counter some room
Lean on the glass, hover over an open box, or park six relatives at the rail and nobody can work. Leave space for the dealer to move trays, use a loop, and talk privately. Extra people can wait in the shop or the car unless they are needed to decide.
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.
If you set a time, be on it
Some shops work by appointment on bigger lots. Be on time. Call if you are late or cannot come. The slot they held is time they did not give someone else. Reliability gets you invited back.
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.
