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.

Silver Age titles dominated the fortnight’s CGC-graded comic sales with $742K, followed by Bronze Age at $551K, while Modern and Golden/Platinum eras trailed with $335K and $230K, respectively.

From May 20 to June 2, 2025, GPAnalysis recorded $4.86M in CGC-graded comic sales across 19,669 books, with Amazing Spider-Man (1963) leading in volume and a CGC 0.5 Superman #1 (1939) selling for $66,000 via HA.com.

A market led by Spider-Man, driven by history, and thriving on both grails and $93 grabs — the stack never sleeps.

The late 1980s and early 1990s are often remembered as the "foil cover" years—overproduction met frenzied speculation, and when the bubble burst in the mid-90s (helped along by a recession), entire comic shops folded seemingly overnight.

From horror roots to modern hits, each decade has its standout, but only one dominates the narrative. With four straight wins and six total appearances, no title comes close. These aren’t just top sellers; they’re trendlines. For collectors, they signal what endures — and what leads.

In the most recent fortnight, GPAnalysis reports $4.4M in sales from 19,568 individual books across major venues offering CGC-graded comics, magazines, and pulps. The most traded title was Amazing Spider-Man, The (1963), which saw 1,261 books sold, totalling $0.6M in sales.
