Street is not on file. The pin is the ZIP or city area — not a door.
Collector notes
Visiting a coin shop
A few notes before you walk into Neptune GBX in 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.
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.
No magnets, acids, or scratch tests on the pad
The shop has the tools if a test is needed. Do not perform experiments on the glass. You can damage the coin and the counter. If you think something is fake, say why and let them look.
Never step behind the counter
That side of the glass is staff only — even if you “just want to show them something in better light.” Hand the coins across. Wait to be invited if they have a viewing area. Crossing the rail uninvited is how visits end early.
When metals jump, the shop gets busier
A sharp day in gold or silver fills the parking lot. Offers take longer. Lines get real. If you can wait a quieter day, you will get a better conversation. If you cannot, bring patience and a simple list of what you have.
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.
