Collector notes

Visiting a coin shop

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 Do not offer to buy their coins, do not quote a price over their shoulder, and do not ask the shop to “introduce you.”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

   Bring coins in a way they can actually look at them

   Trays, albums, and labeled bags beat a torn grocery sack. Do not pour coins onto glass. Hand them a box they can work through. Dirt, food, and loose batteries in the same tin make a poor first impression and a slower look.

3. 03

   Cash is still common. That is normal.

   Coin and bullion shops have worked in cash for a long time. It is not shady by itself. Count together at the counter. Do not count a stack in the parking lot with the door open. If you are uncomfortable carrying cash, say so and ask what else they can do.

4. 04

   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.

5. 05

   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.
