Collector notes
Visiting a coin shop
A few notes before you walk into Grandpas coins in Vallejo, 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.
Saturday morning is often the busy window
That is when collections walk in and regulars stop by. Fine if you like energy. Less fine if you want a long, quiet look at an estate. Midweek late morning is often easier. If you need time, ask when they are slower.
If you feel rushed, you can pause
You are allowed to say you need a minute. You are allowed to pack up and think. You are not required to decide while someone is waiting behind you — step aside and let them go. A good shop would rather you be sure than sorry.
Online asking prices are not what a shop pays
A listing, a completed auction before fees, and a dealer buy price are three different numbers. Screenshots of asks are not a bid. Bring the coins. Let them look. Then talk. You will get further than arguing from a tab on your phone.
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.
Not every coin shop is a pawn shop
Some do jewelry and scrap. Some do not. Ask if you have gold jewelry, a watch, or diamonds. Do not assume, and do not be put out if coins are what they do. The right shop for coins may send you next door for the rest.
