Frequently Asked Questions
What is 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.
Where do your sales come from?
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.
How do you calculate “Estimated Worth (Fair Value)?”
Fair value blends recent realized sales with longer-term trends, outlier filtering, and grade-level
liquidity. It’s an informational estimate, not an offer.
How often are values updated?
Values update as new sales appear. Each grade’s “Updated on” date reflects the most recent sale we’ve
matched for that grade.
Which grades do you cover?
We track Universal CGC-graded copies across common scale points (e.g., 0.5–10). Availability varies by
issue and observed market activity.
Do you offer investment advice?
No. Underval provides data and estimates for research purposes only. Always do your own diligence before
buying or selling.
