The Most Expensive Comic Books Ever Sold

A comic book that cost ten cents off a 1938 newsstand is now the most valuable printed pop-culture object on earth. The numbers below aren't theoretical — they're real sales, most of them at public auction, and the list keeps getting rewritten. We update this page every time a new record falls.

Here are the headline figures, then the stories — and at the end, the four things that separate a $15 million comic from the stack in your closet.

The record holders

Prices rounded. Private-sale figures are as reported by the brokers involved; buyers and sellers are often anonymous, so treat the top line as reported rather than independently confirmed. Public-auction results are hammer-plus-premium totals.

The attic Superman that broke the record

The best story on the list is also one of the most expensive. In late 2025, three brothers cleaning out their late mother's San Francisco home found a copy of Superman No. 1 (1939) in a cardboard box in the attic, buried under brittle newspapers and cobwebs. Their mother and her sibling had bought a handful of comics on the eve of World War II and forgotten them for the better part of a century.

Northern California's cool, stable climate did what a vault would have: the spine stayed firm, the colors stayed vibrant, the corners stayed crisp. CGC graded it a 9.0. In November 2025, Heritage Auctions sold it in Dallas for $9.12 million — at the time, the most expensive comic book ever sold at public auction.

It's the kind of find that sounds made up, and it happens more often than you'd think. Which is exactly why it pays to actually check what's in the box before it goes to the curb.

Why Action Comics #1 sits at the top

Nearly every record on this list is one of two books: Action Comics #1 or Superman No. 1. That's not a coincidence. Action Comics #1 (June 1938) is the first appearance of Superman — the issue that effectively invented the superhero genre. Almost no high-grade copies survive; wartime paper drives and the simple fact that nobody saves a dime comic mean most were pulped or read to pieces.

So you have the single most historically important comic in existence, in a grade almost no one else can match. A CGC 8.5 copy sold for $6 million at public auction in 2024. In early 2026, a 9.0 copy reportedly changed hands privately for around $15 million — brokered by Metropolis Collectibles and ComicConnect, with both parties anonymous. If confirmed, that's the highest sum ever paid for any comic book.

The Marvel side has its own crown jewel: Amazing Fantasy #15, the first appearance of Spider-Man. A CGC 9.6 — one of only a few known in that grade — sold for $3.6 million at Heritage in 2021.

What actually makes a comic worth a fortune

You'll notice the same forces behind every number above. They're the same ones that decide whether your comic is worth $8 or $80,000:

• First appearance / key issue. The first time a major character shows up is the single biggest value driver. Action #1, Amazing Fantasy #15, Batman #1 — all firsts.
• Grade. Condition is everything at the top. The difference between a CGC 8.5 and a 9.0 of the same book can be millions of dollars. Professional grading (CGC, CBCS) turns "looks nice" into a number buyers trust.
• Scarcity. How many survive, especially in high grade? Old comics were printed to be thrown away, so genuine high-grade Golden Age books are vanishingly rare.
• Demand. A character has to matter to today's buyers. Movie and TV announcements routinely send first-appearance issues climbing overnight.

None of these require a million-dollar book to matter. The same checklist tells you whether a $40 bronze-age key in your long box is quietly worth a few hundred — and whether it's heading up or down right now.
