Built by a collector,
for collectors.
PSA submissions cost real money. A bad centering read can mean the difference between a PSA 10 and a PSA 8 — and hundreds of dollars in value. 401PokeCards was built to take the guesswork out of that decision.
This tool exists because we've been on the losing end of a submission we knew wasn't quite right but submitted anyway. Never again.
What Is 401PokeCards?
401PokeCards is a Rhode Island–based Pokémon card collecting and grading resource. We focus on PSA submissions across modern and vintage sets — from XY Evolutions and Shining Legends to Scarlet & Violet Special Illustration Rares.
The Digital PSA Grader is our flagship tool: a browser-based centering analyzer that lets you measure your card's Left/Right and Top/Bottom border ratios against official PSA grading standards before you spend a dollar on a submission.
The Tool
The grader runs entirely in your browser. No images are uploaded to any server. No account is required. Your card photo never leaves your device.
Drop a straight-on photo of your card into the tool, drag the border lines to align with the outer card edge and inner art box, and get instant centering ratios with a PSA grade range verdict. Use the 5× precision loupe to nail edge placement, nudge rotation to straighten tilted photos, and export your analysis as a PNG.
PSA Centering Standards We Use
The tool applies PSA's published centering thresholds: 55/45 front and 60/40 back for a PSA 10; 60/40 front for a PSA 9. These standards are displayed in the grader's reference panel and built into the live grade verdict logic.
Centering is only one grading factor — surface, corners, and edges all matter too — but it's the one you can objectively measure from a photo before you submit.
Sets We Focus On
Our collecting focus spans multiple eras: XY (Evolutions, Roaring Skies), Sun & Moon (Shining Legends, TAG TEAM GX era Rainbow Rares), and Scarlet & Violet (Special Illustration Rares, Special Delivery promos). We evaluate centering across all of these and use this tool daily.
