Surging Cards

How to read this page

Surging Cards tracks PSA 10 graded cards whose WEB2 sold median (eBay / TCGPlayer) has risen significantly over the past 7 days. WEB3 PSA 10 shows the latest PSA 10 median sold price on tokenized / alt-venue platforms (Courtyard, Phygital, CollectorCrypt, Renaiss, SNKRDUNK, Beezie) for the same card — both sides are locked to PSA 10, so lag % reflects a true same-grade price gap (0–100%). Velocity indicates recent trading activity: HOT (10+ trades), WARM (5+), or COLD. Scores combine surge magnitude, lag size, volume, and data reliability.
