He would rise to the title of 'Avenger', but before that, Dr. Hank Pym was the 'Man in the Ant Hill'! Ant-Man makes his comic debut in this sci-fi spectacle, penciled by Kirby. After toying with a size-reducing serum, Pym ill-advisedly tries it on himself...meeting his future insect sidekicks!

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.
