Card photographed inside a rigid holder
Plastic and the case rim hide corner, edge and surface detail, and the holder window can throw off the centering measurement. The grade above is capped at 8 - remove the card from the holder and rescan for a full evaluation.

A grade is only as high as the photo can prove. Retake in sharp focus, out of the sleeve, with even light and no glare — the card may grade higher.

Image Quality Analysis
Fair — 72/100Sleeve/HolderLighting: unevenBackground: business card over dark textured mat
Photo issues
- card_in_holder
- distracting_background
- uneven lighting — part of the card sits in shadow
The card is captured with sharp text details, but photographing it inside a holder introduces surface reflections and shadows that can obscure card details—removing it from the holder ensures our detection AI sees the card directly. Additionally, resting the card on a business card over a dark textured mat creates overlapping edges along the bottom, making it harder for the AI to clearly isolate the card's boundaries. Placing the card directly flat on a plain, high-contrast surface will ensure clean edge detection and the most accurate evaluation.

💡
Not getting the grade you expected?
Your photo quality directly affects the AI's ability to read your card accurately. Here are the most common things that can affect your grade — and how to fix them:
🖼️
Use a plain background
Patterned or colorful backgrounds make it harder for the AI to detect your card's true edges. Place your card on a solid white or light-colored surface before photographing.
🃏
Scan raw cards — no sleeves or toploaders
Penny sleeves and toploaders reflect light and blur fine details. The AI can't accurately assess corners, edges, or surface through plastic. Remove all holders before scanning.
🔍
Fill the frame — get close
The more of the image your card occupies, the more detail the AI can see. Small or distant cards lose corner sharpness and surface detail. Crop in so the card fills most of the photo.
💡
Use even, shadow-free lighting
Shadows, glare, and camera flash create artifacts that look like surface defects to the AI. Use soft, diffused lighting from multiple angles — or scan on a flatbed scanner for the most consistent results.
📐
Keep the card flat and straight
A tilted or bent card distorts centering measurements and can create false edge wear readings. Place the card flat on a solid surface and shoot directly from above.
✅ Fix these issues and rescan — you'll often see better grade on the second attempt. Every credit saves you from wasting a $25–$80 grading submission fee.
