Built for SCALE
Mint Condition™ grades for inventory, not one-off hobby scans.
- Live Grading
- 30 sec per card with no limit.
- Batched Grading
- 100,000s of cards per day.
- Catalog Size
- No limit. We're not fazed by 10M card inventories.
Works on real scans
Centering is trained on penny-sleeved cards and raw unprotected cards. We can still find the card when users scan through a sleeve.
Inventory platforms and marketplaces cannot control how people photograph stock.
- Penny sleeve scans can still get accurate centering and defects when card surface is not covered by glare
- Same API path whether your users sleeve stock or not

Why Mint Condition™ is different
Philip Greenberg built Mint Condition™ to solve a real scaling problem: deciding what to send to grading companies is slow, expensive, and risky. He partnered with Big Tech AI advisors and a development team experienced in insurance damage detection to build pre-grading on a real 150,000+ card collection, not another black-box AI toy.
A lifelong sports fan with a foot in two worlds, Philip manages to bridge the Midwest's fiercest divides as both a die-hard Cubs fan and a Green Bay Packers stock owner. That same passion fuels his career as a serial entrepreneur. As the founder and CEO of Vintage Card Co, Philip has built one of the largest vintage sports card operations on eBay and is a mainstay on the national card show circuit.
With a 150,000+ card personal collection and a deep mastery of trading card economics, Philip founded Mint Condition™ out of necessity. He needed a way to intelligently scale the grading process for his own inventory, leading him to build the very tool he, and the industry, had been waiting for.
