Join hundreds of collectors already using Underval!
Underval is a free comic-book analytics and listings platform. We estimate fair value by grade, display annual growth rate, show recent sales and sales history, and surface active listings.
We aggregate public online sales from major marketplaces and auctions such as eBay and Heritage Auctions, then normalize and de-duplicate them by issue and grade.
Fair value blends recent realized sales with longer-term trends, outlier filtering, and grade-level liquidity. It’s an informational estimate, not an offer.
Values update as new sales appear. Each grade’s “Updated on” date reflects the most recent sale we’ve matched for that grade.
We track Universal CGC-graded copies across common scale points (e.g., 0.5–10). Availability varies by issue and observed market activity.
No. Underval provides data and estimates for research purposes only. Always do your own diligence before buying or selling.
