Collector notes
Visiting a coin shop
A few notes before you walk into Argenteus Rare Coins in Rockville, MD. 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.
Do not clean the coins
Polish, dip, baking soda, and a toothbrush lower the value of most collectible coins. Leave dirt and toning alone. If you already cleaned something, say so. A dealer would rather hear the truth than discover it under a lamp.
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.
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.
One conversation at a time
The dealer cannot price a collection, answer a bullion quote, and pull a date from the case at once. If they are mid-deal, wait. If you only need a quick “are you open Saturday,” say that when they glance up — then step back. Courtesy is remembered the next time you walk in.
Follow the house rules without a debate
Bags on the floor, backpacks zipped, one person at the glass — shops set these for a reason. Argue about it and the visit is already off. If a rule is unclear, ask. If it is clear, do it.
