If this still feels unclear, that’s not your fault
Thor #337 is a perfect example of why comic buying decisions feel harder than they should.
Some grades quietly compound while others stall. Price can look reasonable and still be misleading. And what feels “stable” on a price guide often hides risk that only shows up later.
I struggled with this for years — even on iconic books like this one.
The issue wasn’t access to more data. It was misreading the signals that actually matter when deciding if — and how — to buy.
I documented the framework I now use to make these calls — the same thinking behind Underval’s fair-value logic.
How to stop misreading the comic market before it costs you.

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.
