How it works

Sharpest checks eBay's official listing data twice a day for every product we track. For each one we keep the active fixed-price and best-offer listings from US sellers, add shipping, and remove listings that are not what they claim to be: empty boxes, parts, broken or untested items, fakes, lots, other grades and foreign-language cards.

From what's left we record the lowest price, the 25th percentile and the median, every day, and that is the price history you see. These are asking prices, not sold prices — what you could buy for right now.

A product only gets a page once there are enough clean listings to say something useful.

How we make money

Links to eBay are affiliate links. If you buy through one, eBay pays us a commission; you pay the same price. Rankings are by price alone and are never paid placements.
