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. (with the green bubble in center) Align the Centering50 guides with the card edges and the internal art border. (Optionally: Unlock the image and move/resize/rotate) Get your LR (Left/Right) and TB (Top/Bottom) ratios instantly.

WELCOME BACK TO THE HOBBY. You shouldn't need a padded envelope, a three-month wait, and a prayer to find out what your card is. AOG grades your card in minutes — and shows its work. THE PRAXIS PROTOCOL Every grade runs the same fixed forensic pipeline. Centering is measured, not eyeballed. Corners, edges, and surface are analyzed independently, and a committee of AI models cross-checks the result before your grade is issued. You get a 0–100 composite, four subgrades, and grading notes in plain language — because a grade with no explanation is just a rumor with a number on it. YOUR VAULT Every card you grade or add lives in your vault: filter by sport, search your collection, track values, and mark cards for sale or personal collection. Your cards, organized like they matter — because they do. SLABS WORTH FLEXING Your graded card becomes a digital slab with a scannable QR certificate anyone can verify. Choose from hundreds of slab designs — earn them, open them in packs, or pick them up in the store. Then share the flex. WHAT'S INSIDE - Forensic AI grading with centering, corners, edges, and surface subgrades - Plain-language grading notes on every card - Digital slabs with public QR-verified certificates - A collection vault with search, filters, and value tracking - Hundreds of collectible slab designs and pack openings - Card identification that fills in the details for you THE STRAIGHT TALK AOG grades are AI-powered digital assessments of your photos — built to be consistent, transparent, and explained. AOG is not affiliated with any physical grading company, and a digital grade is not a physical certification. We just think you deserve to know what you're holding without mailing it away. TOKENS & SUBSCRIPTIONS Grading runs on Gold Grade Tokens and slab designs run on Mint Tokens, available through in-app purchases. Optional subscriptions (Collector, Pro, Elite) deliver tokens monthly.

Verdict
The clearest difference is ads: Art Official Grading at none against Centering50's shown. Art Official Grading also leads on rating (5.0 vs 4.7). Centering50's advantage is ratings volume (54 vs 3). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Centering50 sells 3 in-app purchases, starting at $4.99 per month and Art Official Grading sells 10 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Art Official Grading holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Centering50 has 54 ratings behind it against 3, so its average is the more settled of the two.
