Collector notes
Visiting a coin shop
A few notes before you walk into MK Coins in Cambridge, 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.
You do not have to announce what you paid
“I have three thousand in this” is not a grade or a melt value. It puts the dealer on defense and does not change what the coin is. Tell them what it is, where it came from if that matters, and what you want to do. Let the piece speak, then talk numbers.
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.
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.
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.
A hold is a promise. Mean it.
If they hold a coin for you, ask how long and how you pay. Come back or call. Do not park the same piece at two shops. Dealers remember the customer who used a hold as a free option. They also remember the one who did what they said.
