Collector notes
Visiting a coin shop
A few notes before you walk into J & J Coins & Stamps in Hammond, IN. 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.
Ask before you touch anything in the case
The dealer will hand you a coin or put it on a pad. Do not reach into a tray or slide a slab toward yourself. Handle coins by the edges if they are raw. If you drop something, say so immediately.
Keep quiet about another customer’s coins
Do not grade, joke about, or value coins that are not yours. “That’s only a VF” from behind someone who is selling grandpa’s album is not helpful. Look at the cases. Let the dealer run their counter. You will get your turn.
A hold is a promise. Mean it.
If they hold a coin for you, ask how long and how you pay. Come back or call. Do not park the same piece at two shops. Dealers remember the customer who used a hold as a free option. They also remember the one who did what they said.
Decide if you are selling all of it or part of it
“I need this gone” and “I only want to sell the silver” lead to different offers. Decide before you sit down. Changing the goal halfway through wastes their time and yours. It is fine to keep a piece that is sentimental. Say which one.
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.
