About CardFax — The AI Card Grading Engine

CardFax™ pre-grades trading cards straight from eBay and auction listing photos. Right-click a listing's front photo (and the back, if there is one), choose CardFax, and get a condition opinion on the Gem Mint scale in seconds: a likely grade range, a four-quadrant read (centering, corners, edges, surface), and notes on exactly where to look closer before you buy. What you get - A pre-grade range with the most likely grade - Centering, corners, edges and surface read separately, with the area most likely to hold the grade back - Your pre-graded cards saved in one place, synced with your CardFax dashboard - A Bid link back to the listing so you don't loose track of your cards Getting Started - Free: 5 saved pre-grades, swap all 5 every 7 days A pre-grade is an opinion from photos, not a grade. For a registered grade, have the card graded and registered on the CardFax. Available in the United States and Canada. Sign in with Google. Support: hello@cardfax.com Affiliate disclosure: CardFax participates in the eBay Partner Network. When you open an eBay listing using the Bid link inside CardFax and make a purchase, CardFax may earn a commission. This never changes your price and never influences a pregrade.
