Collector notes
Visiting a coin shop
A few notes before you walk into Sentinel Numismatics Store in Milwaukee, WI. 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.
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.
Check hours before you drive
Listings show hours when the shop has shared them. They still change for lunch, shows, and appointments. If you are coming from across town, call or look at the hours on this page. A two-minute check beats a locked door.
Cameras and a locked door are normal
Buzz-in doors, counters, and cameras protect the shop and the people in it. They are not aimed at you personally. Follow the house rules. If you are asked to wait to be let in, wait. That is a well-run store, not a cold shoulder.
A hold is a promise. Mean it.
If they hold a coin for you, ask how long and how you pay. Come back or call. Do not park the same piece at two shops. Dealers remember the customer who used a hold as a free option. They also remember the one who did what they said.
