Northridge Gold Mine and Diamond Buyers

Collector notes

Visiting a coin shop

A few notes before you walk into Northridge Gold Mine and Diamond Buyers in Los Angeles, 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.

1. 01

   Stay with your coins

   Do not leave a box on the counter and wander the cases. Do not ask the dealer to watch your bag while you go to the car. Your lot stays in front of you until the deal is done or you pack up. That is how both sides stay comfortable.

2. 02

   This is a working shop, not a museum desk

   They will talk coins. They will not give a free seminar on forty pieces while a line forms. Pick your best questions. Buy a book if you want to learn the series. A dealer who teaches a little is being generous with the clock.

3. 03

   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.

4. 04

   Large cash deals may require identification

   That is federal law on certain cash amounts, not the shop being nosy. Bring a government ID if you plan to move a lot of cash either direction. A dealer who asks for ID on a large deal is doing the job the right way.

5. 05

   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.
