Collector notes

Visiting a coin shop

A few notes before you walk into American Diamond Exchange, Inc. in New Haven, CT. 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

   Tell them if a coin is damaged, cleaned, or already graded

   Hiding a problem wastes time and trust. “This one was cleaned” or “this already came back from PCGS” is useful. Dealers would rather adjust than feel tricked. Honesty on the small things makes the rest of the visit easier.

2. 02

   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.

3. 03

   Count money together, then put it away

   Whether you are paying or getting paid, count at the counter where both of you can see. Then put it away. That protects you and the shop. If something is off, it is much easier to fix before anyone has left the glass.

4. 04

   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.

5. 05

   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.
