Collector notes
Visiting a coin shop
A few notes before you walk into Great Lakes Coin in Antioch, IL. 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 walk in at closing with a suitcase
Five minutes to close is time to pick up a hold, not to dump an estate. Large lots take time to weigh, look up, and talk through. Call earlier in the day and ask when they can give you a proper look. A shop that is locking the door still has to balance the register and get home.
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.
They do not have to buy what you brought
A shop can pass on tokens, damaged coins, or a category they do not handle. “We don’t buy that” is information. Ask who might. Do not argue them into a box they cannot use. A clean no today keeps the door open next time.
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.
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.
