Diamond State Coins

Collector notes

Visiting a coin shop

A few notes before you walk into Diamond State Coins in Wilmington, DE. 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 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 Do not offer to buy their coins, do not quote a price over their shoulder, and do not ask the shop to “introduce you.”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.

2. 02

   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.

3. 03

   Show week can empty the shop — or pack it

   If the dealer is on the road, the store may be closed or on shorter hours. If they just got back, they may be unpacking. Check this listing for upcoming shows and call if your visit is important. It is not personal. The bourse is part of the business.

4. 04

   Do not ask them to come out to the car

   Bring the coins inside. A dealer should not leave the store to look at a trunk. It is a safety issue for them and for you. If the lot is heavy, make two trips or ask if they have a cart. The work happens at the counter.

5. 05

   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.
