Where war becomes value.

WarCurve is a valuation practice for the modern baseball card market. We measure each player on earned production — career WAR, peak three-year WAR, honors, milestone chases — project the rest of an active career through an aging curve, then weight cultural pull before applying the cardboard hierarchy the market actually pays for: set, parallel, grade, team, era.

The forward curve is fit on a hundred and eighty days of rolling-median comps, tilted by fundamentals, refreshed daily. Nothing is guessed. Every input is documented in the Doctrine.

We publish the methodology in full because a number is only as defensible as the argument behind it. Read the ten papers; the valuation engine and the live surfaces on this site are built against them, line by line.
