Comic Book Appraisal FAQ
How do I appraise a comic book online for free?
Upload a clear photo of your comic to ComicMintAI. Our AI grades its condition and estimates its market value from recent comparable sales — a complete online appraisal in seconds, free on the starter plan.
How accurate is an online comic appraisal?
ComicMintAI grades within 0.5 points of CGC 95% of the time, and value estimates are based on real recent sales data. For most buying, selling, and insurance needs this is more than accurate enough; for six-figure keys, pair it with a formal in-person appraisal.
Can I appraise my comics without sending them anywhere?
Yes. The entire appraisal happens online from your photos. Your comics never leave your possession — no shipping, no drop-off, no risk of loss or damage.
What's the difference between an appraisal and a CGC grade?
A CGC grade certifies condition (and encapsulates the book) for a fee after you mail it in. An appraisal tells you condition AND estimated market value, instantly and free. Many collectors use ComicMintAI to appraise first, then send only their best books to CGC.
Where can I get my comic books appraised?
Traditional options are local comic shops, dealers, and auction houses — usually in person and sometimes for a fee. ComicMintAI lets you appraise comics online instantly from any device, for free.
