A steady fortnight of sales saw Silver Age staples hold strong while modern indies and overlooked decades gained quiet momentum across the CGC market.

The next sleeper hit might already be in your longbox — you just haven’t looked at it in a while.

The graded market moved $4.5M across 19,875 slabs with a $92 median. Amazing Spider-Man (1963) led volume at 1,326 sales, while Amazing Fantasy #15 topped the charts at $30K. Silver and Bronze Age keys drove most value, with Absolute Batman (2024) emerging as the standout modern mover.

The fortnight’s $12.2M in graded comic sales highlights Golden Age strength with a record Flash Comics #1 sale, Silver Age stability driven by Spider-Man and Marvel’s core, and steady demand across Bronze and Modern keys. From Superman’s roots to today’s indie breakouts, every era found its moment.

The most recent fortnight of trading underscores both stability and surprise in the graded comic market. With $5.2M in sales across 21,249 slabs and a median price of $91, the market remains robust. From Spider-Man’s ongoing reign to a record-setting Casper sale, the numbers show a market spread evenly across eras yet punctuated by standout moments.

Some comics hit you so hard, not because they blew your mind—but because they were this close to greatness before the plug got pulled. A canceled series, an unfinished arc, a disappearing creative team—sometimes it’s not poor sales or fan reception that buries a comic, but the very real logistics of publishing.

Between August 13–26, 2025, the market saw $5M in CGC sales across 22,000 books, with a $92 median price. Amazing Spider-Man (1963) led volume, and Amazing Fantasy #15 topped sales at $34,800. Silver Age Marvel keys held dominance, while Bronze Age icons and modern indies like Invincible and BRZRKR kept demand balanced across eras.

Let’s be honest: every collector has had that moment—eyes wide at a listing on GPA, heart racing at an auction, palms a little sweaty thinking, “Should I grab this now before it skyrockets?”
But what if the comic you’re eyeing isn’t actually rare, or even meaningful? What if it’s…overrated?

In the most recent fortnight (July 30th to August 12th, 2025), GPAnalysis reports $6.2 million in sales from 21,325 CGC-graded comics, magazines, and pulps.

🕰️ Silver Age – Led by Amazing Spider-Man, Fantastic Four, and Amazing Fantasy.
🦸‍♂️ Golden Age – Batman, Wonder Woman, and Superman maintained strong sales.
💥 Bronze Age – Incredible Hulk and Giant-Size X-Men dominated the era.
📼 1990s – Steady gains from New Mutants and Spider-Man (1990).✍️ Modern Eras – Creator-driven hits like Invincible, Ultimate Fallout, and ASM (2022) led their decades.

Two Marvel heavyweights. Three comic eras. One question that could change how you build your portfolio. Using fresh GPA sales data, we dig into decades of market history to see which franchise is really delivering for collectors in 2025 — but the answer isn’t as straightforward as you might think.

In 2025, GPA data shows mid-grade Silver Age keys (and select Bronze Age issues) are delivering some of the strongest, most stable returns, offering collectors affordable entry points, broad demand, and proven resilience compared to high-grade modern hype.

Let’s face it—most collectors chase heat. First appearances. Movie hype. Multiverse madness. But some comics? They’re hiding in plain sight. Underrated. Under appreciated. Sometimes underpriced. And they’re begging for a second look.

Silver still leads, Spider-Man spans decades, and Superman holds strong.
🔹 Fantastic Four (1961) topped sales at $454K.
🔹 Amazing Spider-Man (1963) sold 1,336 copies across six decades.
🔹 Superman and Detective Comics combined for $103K in Golden Age gains.
🔹 Modern indie hits like Absolute Batman and Monsters pushed 2020s momentum.
🔹 Bronze Age greats brought in $558K from Hulk, Spidey, and the X-Men.

Silver Age sales surged past all others with over $774K in just two weeks, while Bronze Age nostalgia and modern-era momentum kept the market lively across every generation.

From January to June 2025, CGC-graded comic book sales totaled over $107 million across 245,000 slabs, with Silver Age classics, Amazing Spider-Man dominance, and modern key momentum shaping a vibrant, resilient market driven by both legacy and indie titles.

From Golden Age pulps to modern indie hits, the latest GPAnalysis data reveals a dynamic collector market where classics like The Amazing Spider-Man and Fantastic Four continue to dominate in both volume and value, while newer titles carve out surprising spots in the spotlight.
