MintGauge: Centering ± Meter

Is that card centered well enough to be worth grading? MintGauge measures it before you pay to find out. Hold your phone over a card. MintGauge finds the card, takes 10 frames and reports the median left/right and top/bottom ratios, with the uncertainty of the reading. If an edge is unclear, it tells you so and lets you set it by hand instead of guessing. MEASURE • Front and back, unlimited, free • Automatic card detection with a 10-frame median • Every result shows its ± uncertainty and whether the reading was stable • Works from the camera or from a photo you already have • Raw cards, penny sleeves and top loaders FIX ANY EDGE BY HAND, ALWAYS FREE • Drag any of the eight edges, or nudge it one pixel at a time • A magnifier for exact placement • Manual adjustment is never behind a paywall SEE WHERE YOU STAND • L/R and T/B ratios, plus the larger-first form used for thresholds (for example 55/45) • An estimated max grade for centering, compared with the published centering standards of PSA, BGS, CGC and SGC. For example, PSA allows up to 55/45 on the front and 75/25 on the back for a PSA 10. • Where a grader publishes no number, MintGauge uses a commonly cited community value and labels it "≈ community standard". Grades with no reliable source are not shown. KEEP AND SHARE • History of your measured cards, front and back • A clean share card with the ratios and the estimate HONEST BY DESIGN • No ads. No account. No sign-up. • Card photos are processed on your phone and never uploaded by MintGauge. The app sends a photo nowhere unless you share it. IMPORTANT MintGauge estimates centering only. It is not a grade: grading companies also judge corners, edges and surface, and decide the final grade themselves. MintGauge is not affiliated with, endorsed by or sponsored by PSA, Beckett (BGS), CGC, SGC or any other grading company. Their names are used only to refer to their published standards.
