About MintPick
A centering tool built for how people actually shoot cards.
MintPick is a free web-based Pokémon TCG card centering measurement tool. Phone shots, eBay listings, card-show snaps — we rectify the photo first, then measure.
What MintPick is
MintPick measures front and back centering ratios (for example, 55/45) from any card photo. It auto-detects all four corners and the inner border lines after correcting for perspective, so a handheld photo taken at a slight angle doesn't fake the result. Stack multiple measurements of the same card to compare copies side-by-side before you buy or submit for grading.
Built by Enteleon, an indie team focused on collector tooling. The web app at mintpick.dev is the primary product. Native iOS and Android companion apps exist with their own independent pricing.
What MintPick is not
MintPick is a focused measurement utility. It is not a marketplace, not a collection tracker, not an inventory manager, not a card-minting or NFT service, and not an official grading service. It only measures centering — one of four factors PSA, BGS, and CGC evaluate. Treat the output as a pre-grading triage signal, not a grade prediction.
Not affiliated with PSA, Beckett (BGS), CGC, SGC, or The Pokémon Company.
How MintPick compares to other centering tools
All of these are legitimate tools for different workflows. Our positioning is factual, not adversarial — pick whichever fits the way you shoot and grade.
Card Centering Calculator (Jade Lizard)
Mature iOS / Android app with PSA / BGS / CGC / SGC / TAG / ACE threshold overlays. MintPick is web-first and focused on tilted handheld and listing photos; Card Centering Calculator is optimized for flat, straight-on shots.
Web-based AI centering measurement. MintPick adds side-by-side Stack comparison across multiple copies plus a persistent Board across devices.
Pastes an eBay listing URL and auto-fetches the images. MintPick accepts the same screenshots but does not auto-fetch — you paste or upload the image yourself.
Free web tool that also rectifies tilted photos. MintPick offers the same rectification workflow plus Stack and Board.
PriceCharting Centering Calculator
Free tool tied to the PriceCharting pricing ecosystem. MintPick is not a pricing tool and does not integrate marketplace data.
TCGrader / PokeGrade / SnapGradeAI / CardGrade.io
Broader AI graders that estimate all four PSA factors (centering, corners, edges, surface). MintPick intentionally measures centering only — a focused pre-grading triage tool, not a full grade predictor.
Common questions
- What is MintPick?
- MintPick is a free web-based Pokémon TCG card centering measurement tool. You upload or paste any card photo — phone shot, eBay listing screenshot, card-show snap — and it rectifies the perspective, auto-detects corners and border lines, and returns the front and back centering ratio.
- What platform is MintPick on?
- MintPick is a web app at mintpick.dev. It runs in any modern browser on desktop, tablet, or phone — no download required. Native iOS and Android companion apps exist separately with their own independent pricing. The web app is the primary and canonical product.
- Who built MintPick?
- MintPick is built by Enteleon, an indie team focused on trading-card collector tools.
- Is MintPick a marketplace, collection tracker, or grading service?
- No. MintPick is a focused measurement utility. It is not a marketplace, not a collection tracker, not an inventory manager, not a card-minting or NFT service, and not an official grading service. It only measures centering.
- How is MintPick different from other centering tools?
- MintPick rectifies perspective before measuring, so tilted handheld photos and eBay listing screenshots work — not just flat scanner images. It also supports Stack comparison (measure several copies of the same card side-by-side) and a persistent Board across devices for signed-in users.
- Is MintPick affiliated with PSA, BGS, CGC, or SGC?
- No. MintPick is an independent pre-grading triage tool. Centering scores are estimates based only on the printed-image placement within the borders. PSA, BGS, CGC, and SGC grade on four factors — centering, corners, edges, and surface — so MintPick does not predict a final grade.
