Midpoint: Card Prices & Centering Tool

Card prices, PSA 9/10 values and worth-grading verdicts for 1.5M+ trading cards, plus AI centering. Right-click any listing.

Check a card's centering and value before you grade it or buy it. Midpoint puts two tools for trading card collectors in Chrome's side panel. Centering Right-click any card image on a marketplace listing, or add your own photo. Midpoint's model straightens the card and places the measurement boxes on its edge and printed border. Drag any box to fine-tune it. You get the left/right and top/bottom centering and the best grade that centering allows at the major grading companies. You can use the model 3 times a day; after that, you place the boxes yourself. Images are sent to Midpoint's server to be measured and are never stored. Prices Highlight a listing title, right-click and choose "Look up card price", or search in the panel. You see raw and graded market values from real sold listings, refreshed daily, for more than 1.5 million trading and sports cards, plus whether a card is worth sending to PSA. How to use it Click the Midpoint icon to open the side panel. Right-click a card image and choose "Measure card centering", or a listing title and choose "Look up card price". Adjust the boxes if needed and read the result. For a full grade covering corners, edges and surface, plus collection tracking and price alerts, use the free Midpoint app on iPhone, Android or the web at cardcenteringtool.com.
