Collector notes

Visiting a coin shop

A few notes before you walk into Marc One Numismatics, Inc. in Rancho Mirage, 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

   Do not crack a graded holder in the shop

   PCGS, NGC, ANACS, and CAC holders are part of the product. Opening one at the counter to “see it better” can wreck the value. If you want it out, that is a decision you make at home, not a demonstration.

2. 02

   Do not make a deal with another customer at the counter

   If you overhear what someone is selling, that is not an invitation. Do not offer to buy their coins, do not quote a price over their shoulder, and do not ask the shop to “introduce you.” The counter is the shop’s workplace. Side deals in the aisle put the dealer in an ugly spot and make other customers uncomfortable.

3. 03

   Decide how you want to be paid before the offer

   If you are selling, know whether you need cash today, a check, or time to think. Changing the method after they have made a number can change the number. A clear “I would like a check if we agree” at the start saves a second conversation.

4. 04

   Know roughly what you brought

   You do not need to be an expert. A simple list — silver dollars, a few proofs, a bag of wheat cents — helps. “I have no idea, you tell me” on a mixed box is fine once. It is harder when the box is huge and you cannot say what you want out of the visit.

5. 05

   Check hours before you drive

   Listings show hours when the shop has shared them. They still change for lunch, shows, and appointments. If you are coming from across town, call or look at the hours on this page. A two-minute check beats a locked door.
