A few simple habits will give you the best card identification and pricing accuracy CardMint can produce. Here's everything you need to know before you start scanning.
Best practices
Natural daylight works best. Avoid harsh overhead light, flash, or standing so your shadow falls across the card — it washes out text and makes the year hard to read.
Get close enough that the card takes up most of the photo. A large, centered card gives the AI the most detail to work with — especially for the copyright year and card number.
Hold your phone directly above the card, parallel to its surface. Angled photos distort the player image and make the fine print harder to read.
Chrome, Prizm, and refractor cards are extra reflective. Tilt the card slightly to kill any glare covering the player name, set logo, or card number.
The back of the card is where the copyright year, card number, and set name usually live. Scanning both sides dramatically improves accuracy.
If you already know what set a card is from, pick it from the dropdown before scanning. It helps the AI narrow down the year and parallel more reliably.
Common mistakes
A quick tap on the card in your camera app to refocus makes a huge difference. Blurry images almost always cause the AI to guess the year or misread the card number.
Many modern sets don't put the year on the front of the card. Without the back, the AI has to infer the year from design cues, which is where errors tend to happen.
Tungsten bulbs and dim rooms tint the photo and hide fine print. If you can, scan near a window or under a daylight lamp.
Penny sleeves are fine. Top-loaders and one-touches often produce glare bands across the card. Angle the card slightly until the glare shifts off the printed area.
Cut-off borders, card numbers, or copyright text force the AI to guess. Include the full card in the frame, borders and all.
CardMint's identification is powered by AI and, while generally reliable, it is not 100% perfect. Years, parallels, and card numbers are the fields most commonly misread, especially on older cards or photos with poor lighting. Value estimates are approximations based on recent market data and should not be treated as professional appraisals. Always double-check high-value cards against official grading services and recent sold comps before buying, selling, or insuring them. You can edit any field on a card after scanning — if something looks wrong, fix it in one click.
Sign in and head to the scanner — the set dropdown and a good photo will get you the best results.

Free accounts get up to 5 cards. Upgrade anytime for more.
Questions
We use Claude Vision in two passes — first to read the card, then to verify against active eBay listings. Identification is highly accurate for modern cards (2010+) and continues to improve.
We pull data directly from eBay sold listings and active listings via the official eBay API. When data is sparse, we fall back to an AI estimate (clearly labeled).
Yes — you can edit every field, replace the front or back image, and re-run pricing at any time. You can only edit cards you own.
Cards you mark as public appear on the shared "Card Collection" tab so the community can browse them. Only you (or an admin) can edit or delete your cards.
