HSA Pre-Grade Pro
Pixel-perfect AI pre-grading
HSA Pre-Grade Pro is built for serious hobbyists and collectors who want a rigorous, data-backed read on a card before it ever goes in an envelope. Its computer vision framework standardizes the assessment of centering, corners, edges and surface, so you get a consistent screening checkpoint instead of a gut feeling.
What it scans
Four criteria, measured the same way every time
Upload a high-resolution image of the front and back of your card. The scanning structure examines it down to the microscopic level and reports what it finds on each of the four criteria graders care about.
Centering
Border widths are measured on all four sides and compared as a ratio, so off-center cards are caught before they cost you a submission fee.
Corners
Each corner is inspected at high magnification for softness, fraying and whitening that the naked eye reads as sharp.
Edges
Edge lines are traced for chipping, nicks and print wear along the full perimeter of the card.
Surface
Surface passes look for scratches, print lines, dimples and gloss breaks across the front and back.
Why collectors use it
Grade smarter before you spend
In modern trading card and sports card markets, accuracy is everything. Screening first means fewer surprises when the grades come back.
Objective, repeatable results
The same card scanned twice is assessed the same way. Standardizing the read removes the human bias and fatigue that creep into manual inspection.
Protect your grading budget
Screen your inventory first and filter out flawed cards, so the cards you actually mail in are the ones worth grading.
Built for volume
High-volume hobbyists can work through a stack of raw cards quickly and sort submissions with confidence instead of guesswork.
