About Coinsel

Coinsel is a price-intelligence platform for graded coins and currency. Built for collectors who want real data (PCGS price guides, live eBay listings, auction results) instead of guesswork.

What Coinsel Does

Most collectors already know what a coin should be worth. The hard part is finding out what it’s actually selling for right now. And that means bouncing between a price guide, a stack of eBay sold listings, and an auction archive, then doing the math in your head.

Coinsel puts those sources side by side. PCGS guide values, live and recently sold eBay comps, and auction results for the same coin in the same grade, in one view, so the gap between guide price and street price is obvious instead of buried. It’s the difference between “the guide says $340” and “the guide says $340, but eleven have sold in the last 90 days between $255 and $290.”

Coinsel is a free to use tool that makes it easy to find the current market value of any coin. We aggregate recent sold listings from eBay and auction results from GreatCollections, then calculate a fair market value for each coin based on that data. You can see the current market value of any coin, along with a history of its sales, all in one place.

Create an account today, to build a watchlist of the coins you’re tracking, save searches you run often, and find dealers and shows near you. Whether you’re buying, selling, or just deciding whether that auction lot is worth a bid, you’ll have access to the same data the people across the table are using.

The Story

Collectors collect. But most collectors get tired of the same routine every time they consider a purchase: open the price guide, open eBay, filter to sold listings, squint at grades, scroll an auction archive, and try to hold four numbers in my head at once. More than once, like most collectors do, I paid too much because the guide value was stale, or passed on something good because I couldn’t tell fast enough that it was underpriced.

So I started tracking it manually. Guide value in one column, recent sales in the next, the spread in a third. That spreadsheet got unwieldy fast, and it turned out the useful part wasn’t the numbers themselves but seeing them together.

Coinsel is that spreadsheet, rebuilt properly. Same idea: pull the data collectors are already checking one tab at a time, put it in one place, and let the numbers speak for themselves.
