Net = sale × (1 − selling fee) − grading fee − shipping. A cleaned or damaged coin can come back in a details holder — often worth less than raw.

How the math works

Grading is a bet: fixed cost in, uncertain grade out. The calculator weighs each outcome by honest odds, subtracts every cost, and compares against just selling the coin raw. Find comps by searching sold listings for your coin at each grade on eBay or GreatCollections.

FAQ

Where do I find graded comps?
Sold listings on eBay and GreatCollections archives — use the median of recent sales at each grade, not the best one.
Does the calculator include membership?
Not automatically — spread your membership across the batch and add it to the fee. Fee details on the cost page.
