Centering50: TCG & Sports Card Grading Tool Stop guessing and start grading with confidence. Whether you are a hardcore Pokémon TCG investor, a sports card flipper, or a casual collector, centering is the #1 reason cards fail to hit a Gem Mint 10. Centering50 is the professional-grade scanner designed to help you predict your grade before you spend a cent on submission fees. WHY CENTERING MATTERS In the modern hobby, the price gap between a PSA 9 and a PSA 10 can be thousands of dollars. Professional graders at PSA, BGS, SGC, CGC, and TAG use digital precision to measure border ratios. If your card is even 2% off, you lose the Gem Mint dream. Centering50 brings that same laboratory precision to your smartphone. PRECISION FEATURES FOR COLLECTORS: "Smart-Snap AI: Our algorithm helps you detect card borders for lightning-fast scanning of modern Pokémon, Magic: The Gathering (MTG), Lorcana, and One Piece cards. Save time with AI-assisted alignment, then fine-tune for 0.1% precision." Auto-Straighten Technology: Don't worry about perfect alignment. Scan at any angle and the app will instantly fix the tilt. The "Magenta Line" Manual Mode: For vintage cards or thick-bordered sports cards (Topps, Panini, Upper Deck), use our high-contrast measurement guides to set your own anchor points with 0.1% accuracy. Grading Standard Library: Instantly compare your results against the official 2026 standards: PSA: 55/45 Front (New 2025 Standard) BGS: 50/50 for Black Label eligibility SGC & CGC: Real-time centering thresholds Front & Back Analysis: Don't get rejected for a 90/10 back! Measure both sides independently to ensure your submission is truly "Perfect." 15x Precision Zoom: Perfectly align your guides on thin silver or gold borders with our enhanced magnification tool. SAVE MONEY ON SUBMISSION FEES Sending cards to be graded is expensive. Why pay for a "Near Mint 7" when you could have known the result at home? Use Centering50 to filter your collection and only send your strongest candidates. It’s the ultimate pre-grading utility for: Pokémon TCG (English & Japanese) Sports Cards (Basketball, Baseball, Football, Soccer) Disney Lorcana & One Piece TCG Yu-Gi-Oh! & Magic: The Gathering DESIGNED FOR THE 2026 HOBBYIST We know you’re scanning in different lighting. Our app features Dynamic Contrast Adjustment and Skew Correction, so even if your photo is slightly tilted, our math remains perfect. HOW TO USE: Place your card on a high-contrast, flat surface (no sleeves for best results). Take a photo directly from above.

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. Choose a monthly or yearly subscription (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 current period. 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.

Verdict
The clearest difference is rating: CenterMint at 5.0 against Centering50's 4.6. CenterMint also leads on update cadence (every 4 days vs every 8 days). Centering50's advantage is ratings volume (41 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
