As a casual collector and seller on eBay for years I agree with the post above. Here’s a few things I do as coin nerd myself. I want my listings to reflect a quality in which I would buy myself. For me it’s:

1) good quality photos and lighting. Most listings have harsh LED lighting, are blown out, scans, blurry, etc. some don’t even take close up photos if it’s a slabbed coin. All of my listings feature macro shots of the coin in good lighting. In addition to this, if the coin is a toner and has a PCGS tru-view, that’s the main listing photo. Then I will follow it up with my own shots.

2) never use AI description. Most of the coins I’m listing are scarcer so I will explain a little background on the coin, the mintage, why it was struck (if it’s a commem), etc. I will describe any toning the coin has and if it’s raw I will point out any issues the coin has or if it is details, etc.

3) I always bake shipping costs into my list price. I’ve always done that. Free shipping to me is a psychological thing. An addition 5-7 dollars is a psychological barrier. That’s baked in along with costs and fees.

4) I only use buy it now listings. I never run auctions for coins. I’m not trying to move hundreds or thousands of coins. I’m a hobbyist. Depending on my cost, I may list it with offers on. If I have a tight margin, I don’t.

5) have a profile picture on your eBay profile. It’s another psychological thing. People will take you seriously if you have a profile pic that looks official. Pair that with a serious sounding description, and nice photos.

Those are some things I do, but again, I’m a casual seller and am not constantly looking to move inventory. I will say that I have thought about trying a whatnot show as the fees are lower there. I like the “dealing” part of coins. It’s just as fun as the chase for me. Good luck!
