Collector notes
Visiting a coin shop
A few notes before you walk into The Gold Mine, Inc. in Sioux Falls, SD. 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.
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.
What is in the case today may be gone tomorrow
Coin shops turn inventory. A picture from last month is not a hold. If you want a date or a grade, call or start a want list. Showing up and hoping the exact piece is still there is how people get disappointed.
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.
When metals jump, the shop gets busier
A sharp day in gold or silver fills the parking lot. Offers take longer. Lines get real. If you can wait a quieter day, you will get a better conversation. If you cannot, bring patience and a simple list of what you have.
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.
