Is this card worth grading, and what is it worth? Measure its centering from one photo, then see what it sells for in Japan, the US and Europe. CenterMint finds the cut edge and the printed border on all four sides of a raw card, shows the left/right and top/bottom ratios, and tells you the best centering grade they allow under common published standards (PSA, BGS, CGC and more). Works with standard-size cards such as Pokémon, One Piece, Magic: The Gathering and sports cards; smaller cards like Yu-Gi-Oh! can be measured too. NEW IN 2.0 • Japanese Pokémon card prices: more than 30,000 cards, from promos and high rarities to Master Ball mirrors. Pick your market (Japan in yen, the US in dollars, Europe in euros) and see recent sales and a 30-day chart. • English version prices too, when it is clearly the same card, so you can tell which print is cheaper. • No recent sales? It says so and shows a shop price or the lowest listing, clearly labeled, instead of guessing. • Follow cards and get a price alert when one moves 5%, 10% or 20% (you choose). Alerts on 3 cards are free. • Worth Grading? now finds the card in the catalog and fills in its prices for you. • Line styles made for the card in your hand: white borders, black borders and foil. • The app speaks 15 languages. Prices are for reference only, not buying or selling advice. HOW IT WORKS • Take a photo or import one. The frames are found automatically. • Not sure about a line? CenterMint takes you to the least certain one first, with the magnifier already on it. Tap "Looks Right" to move on, or nudge it a pixel at a time with the magnifier, pixel grid and edge profile. • Save the front and back as a pair, search your history, and share a clean image. FREE • Automatic centering for raw cards, a 1x–50x magnifier and manual adjustment • Border widths in mm or inches • Corner and edge close-ups on 3 cards a week, one batch of up to 5 photos a week, Worth Grading? on one card • Card prices, the 30-day chart and alerts on 3 cards The free version shows ads. CENTERMINT PRO No ads, graded prices (PSA 10, PSA 9 and more) with full history, unlimited price alerts, Worth Grading?, corner and edge close-ups, a submission log, a decision assistant that sorts cards into submit / fix first / below target, batch scanning of up to 50 photos, a submission checklist PDF, report images, 4K enhanced view and export, CSV export and saved presets. Choose monthly or yearly (yearly starts with a 1-week free trial); prices are shown in the app. Subscriptions renew automatically unless canceled at least 24 hours before the end of the period. Manage them in your Apple Account settings. GOOD TO KNOW • Automatic measurement is for raw cards. For a card in a sleeve, top loader or slab, you line up the edges yourself; CenterMint tells you when it sees a sleeve. • It measures centering only. Corners, edges and surface are for your own eyes, and no grade is ever promised. • Centering standards are references based on each company's published guidelines. CenterMint is an independent app, not affiliated with PSA, Beckett (BGS), CGC or any grading company, or with any card publisher. Pokémon, One Piece, Yu-Gi-Oh! and Magic: The Gathering are trademarks of their respective owners. Measurement runs on your device and needs no account.
