Collector notes
Visiting a coin shop
A few notes before you walk into Professional Coin Center in Groton, CT. 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.
You do not have to announce what you paid
“I have three thousand in this” is not a grade or a melt value. It puts the dealer on defense and does not change what the coin is. Tell them what it is, where it came from if that matters, and what you want to do. Let the piece speak, then talk numbers.
Bullion and collector coins are different conversations
Melt moves with the market. A key date does not. Say what you think you have, then let them look. Mixing “it’s old so it must be rare” with a junk-silver bag slows everyone down. Sort in your mind: weight versus date.
Tell them if a coin is damaged, cleaned, or already graded
Hiding a problem wastes time and trust. “This one was cleaned” or “this already came back from PCGS” is useful. Dealers would rather adjust than feel tricked. Honesty on the small things makes the rest of the visit easier.
Ask if they buy the whole lot or select pieces
Some shops write one number for the box. Some pull the coins they can use. Neither is wrong. Ask which they do before they start. If you need everything gone today, say that. If you only want to sell the silver, say that too.
