Is this card worth grading? Check its centering, corners and edges before you pay to find out. CenterMint measures the centering of raw trading cards and sports cards from a single photo. It finds the card's cut edge and printed border on all four sides, shows the left/right and top/bottom ratios, and tells you the best centering grade those ratios allow under common published standards (PSA, BGS, CGC and more). Works with raw standard-size cards such as Pokémon, One Piece, Magic: The Gathering and sports cards; smaller cards like Yu-Gi-Oh! can be measured too, but check the lines. NEW IN 1.11 • Border widths in mm or inches under every ratio (or off). The card size is detected from the photo, sports cards and the smaller Yu-Gi-Oh! size included. Free for everyone. • Corner & edge close-ups now sit right under your result, with thumbnails of all four corners. Free on 3 cards every week. • Free users get a batch of up to 5 photos every week. • A sharper, redrawn app icon. KEY TOOLS • Line-by-line check: when a photo needs a second look, CenterMint takes you to the line it's least sure about first, with the magnifier already in place. Tap "Looks Right" to move to the next one. • Know why: glare, blur, low light, low resolution, a mat that matches the card edge, or no printed border found. If a retake will fix it, it says so. • Worth Grading? (Pro): enter recent sold prices for the raw card, a 9 and a 10, plus the grading fee. See whether grading makes or loses money, and what a 10 has to sell for to break even. Grades the centering can't reach are left out. • Submission log (Pro): note what you sent and what it cost, add the grades when they come back, and see your top-grade rate and how the grades compare with the centering. FREE • Automatic centering for raw cards, a 1x–50x magnifier and manual line adjustment • Line-by-line check and retake tips • Front and back pairing, saved history with search, and share images • Border widths in mm or inches, close-ups on 3 cards every week, a batch of up to 5 photos every week, and Worth Grading? on one card The free version shows ads. CENTERMINT PRO No ads, Worth Grading?, corner & edge close-ups, submission log, a decision assistant that sorts your cards into submit / fix first / below target, batch scanning of up to 50 photos, submission checklist PDF, report images, 4K enhanced view and export, CSV export and saved presets.

Manage them in your Apple Account settings. WHAT IT DOESN'T DO • Automatic measurement is for raw cards only. For a card in a sleeve, top loader or graded slab, you line up the four edges yourself. When CenterMint detects a sleeve, it tells you and switches to manual alignment. • It measures centering only. It doesn't grade corners, edges or surface (the close-ups are for your own eyes), and it can't promise any grade. • Full-art and borderless cards may have no printed border, so their results are a reference. • Centering standards are references based on each company's published guidelines. CenterMint is an independent app and is not affiliated with PSA, Beckett (BGS), CGC or any grading company. It is not affiliated with any card publisher either; 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. Sharing samples to improve detection is off by default. App languages: English, Japanese, Korean, Vietnamese, Simplified Chinese and Traditional Chinese.
