Sports card scouting

Everything we publish here starts with the same question collectors ask us inside the Radar app: what is this card actually worth, and what should I do with it? The answers in most search results are either a price-guide paywall or a list recycled from the same three sources. We write the version we wanted to read — built on real eBay sold listings, public auction records, and the grading population data that actually moves prices.

Radar is a card scanner: point your camera at a card and it identifies the player, set and parallel, then shows you what that exact card has been selling for. Working on that engine means we spend our days inside sold-comps data — watching which 1980s Topps cards actually clear four figures, how much a PSA 10 premium really is over a raw copy, and which "valuable" cards from the junk-wax era still trade for a dollar. These guides are where we write that perspective down.

What you'll find here: value guides for the sets and players people search for most — with honest numbers, not wishful thinking; grading explainers that tell you what PSA, BGS and SGC actually charge and when grading is worth the fee; and market research on where card prices are moving. Every price we quote is framed the way we'd want it framed as buyers: recent sold ranges, not decade-old book values and not asking prices that never clear.

New guides land every week. If a card is sitting in front of you right now and you just want the number, the fastest route is the scanner itself — free on iPhone and Android. If you want to understand the market before you buy, sell or submit to grading, start with any guide below.
