Collector notes
Visiting a coin shop
A few notes before you walk into Coin Tech in Burlingame, 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.
Wait your turn at the counter
A coin shop is not a buffet line. The person already at the glass is in a private conversation. Stand back, keep your box closed, and wait to be invited forward. Jumping in with “real quick” questions while someone is selling a collection is the fastest way to start a visit on the wrong foot.
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.
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.
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.
Shopping an offer is etiquette when you are honest
“I want to hear one more shop, then I will decide” is adult. “I already promised it to you” when you have not is not. If you come back, say what changed. Dealers respect a straight process. They do not respect being used as a foil.
