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 PokΓ©mon, One Piece, Magic: The Gathering and sports cards; smaller cards like Yu-Gi-Oh! can be measured too, but check the lines. NEW IN 1.9 β€’ 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. β€’ 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. β€’ 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. β€’ Corner & edge close-ups (Pro): all four corners and all four edges cut from your original photo at full resolution, so you can look for whitening and dings. Share them as one image. β€’ 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. ALSO NEW β€’ A new iOS 27 design, more accurate measurement of gold and silver borders and on cloth or wood backgrounds, Loupe 2.0 (real pixels, edge profile), Batch 2.0 with burst shooting (Pro) and a submission checklist PDF (Pro). Measurements always use the photo's full resolution, on the free plan too. FREE β€’ Automatic centering for raw cards, a 1x–50x magnifier and manual line adjustment β€’ Line-by-line check and retake tips β€’ Front and back pairing, saved history with search, and share images β€’ Try Worth Grading? and close-ups on one card, and one batch of up to 5 photos The free version shows ads.

Manage them in your Apple Account settings. WHAT IT DOESN'T DO β€’ 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. β€’ 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. β€’ Full-art and borderless cards may have no printed border, so their results are a reference. β€’ 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; PokΓ©mon, 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 and sharing usage statistics are both off by default. App languages: English, Japanese, Korean, Vietnamese, Simplified Chinese and Traditional Chinese.
