The Galactus Trilogy — Fantastic Four #48, #49, and #50 (1966) — remains among the most significant Silver Age keys in all of Marvel, yet their all-grades eBay median hovers around €9–14 (64 to 100 active listings in June 2026). That gap between historical importance and entry price makes them the archetypal undervalued issues for the patient collector.

Launched in November 1961 by Stan Lee and Jack Kirby, Fantastic Four #1 laid the foundation for what we now call the Marvel Silver Age. Reed Richards, Sue Storm, Johnny Storm, and Ben Grimm formed the first superhero family at the House of Ideas — and their 1960s run concentrates some of the most important keys in the entire history of American comics. Yet several of those issues still trade at surprisingly low entry prices on eBay.

This guide relies exclusively on verifiable data: eBay medians from our estimator (eBay.fr + eBay.com, June 2026) and sale records documented by Heritage Auctions, GoCollect, and ComicLink. Where a precise figure cannot be verified, we state it qualitatively rather than inventing it.

The Galactus Trilogy (#48–50): maximum importance, minimal entry price

Fantastic Four #48 (March 1966) contains the first appearance of the Silver Surfer and a cameo by Galactus — two characters who feature prominently in the MCU film The Fantastic Four: First Steps (released July 25, 2025). Yet our estimator returns an all-grades median of €9 across 98 active listings. FF #49 delivers the first full appearance of Galactus: same result, a €9 median across 64 listings. FF #50, the arc's conclusion, shows a slightly higher median — €14 across 100 listings.

Why the disconnect? The all-grades eBay median folds in dozens of modern reprints, foreign editions, and very low-grade copies. An original in decent condition trades well above that floor. In high grade, FF #48 reached $192,000 (CGC 9.8, 2022, Heritage Auctions) — a multiple of several thousand times the eBay median. That gap is precisely what defines an undervalued issue: the entry is cheap, the ceiling is enormous.

Fantastic Four #5: the first Doctor Doom for under €10

Published in July 1962, Fantastic Four #5 is the first appearance of Doctor Doom, the team's defining adversary and one of Marvel's most iconic villains, created by Stan Lee and Jack Kirby. Our estimator returns an all-grades median of €9 across 99 active listings — a liquid, telling signal. As with the Galactus Trilogy, that median includes reprints and low-grade copies. In high grade, Heritage Auctions realized approximately $180,000 for a CGC 9.2 in a 2022 sale. The spread between the eBay entry median and the documented record perfectly illustrates Silver Age market logic: access is open to everyone; extreme value belongs to authenticated high-grade originals.

Fantastic Four #112: the Bronze Age Hulk vs. Thing showdown

Published in July 1971, Fantastic Four #112 is celebrated for the brutal clash between the Thing and the Hulk — "Battle of the Behemoths!" — one of the most talked-about fights of the Marvel Bronze Age. Our estimator returns 22 active listings, with a low of €9 and a high of €93. With only 22 listings, the market is thinner than the headline Silver Age keys: figures reflect more limited supply. In high grade, a CGC 9.8 copy sold for about $24,000 in 2009 (SellMyComicBooks/Heritage), and the only known CGC 9.8 copy has never been offered at public auction.
