JOURNEY INTO MYSTERY #100

Cover shows moderate wear consistent with a mid-grade Silver Age book: visible spine stress lines and slight whitening along the spine, a small stress crease near the top-left corner, and general handling wear at the corners with slight rounding. The cover gloss appears diminished with minor surface wear, and there's a faint vertical crease running through the lower portion of the cover. The comic is in a protective sleeve which creates some glare and reflections that may obscure finer details of wear. Interior pages and back cover were not visible for assessment.

Journey Into Mystery #100, cover-dated January 1965, arrived at the height of Marvel's Silver Age expansion of the Thor mythos. By this point the series, originally a suspense/anthology title, had been carried for years by Stan Lee's scripts and Jack Kirby's art on the Thor feature, and the 100th issue was positioned by Marvel as a milestone within the ongoing saga of Asgard, Odin, and Loki. While the issue does not carry a first appearance or origin story, it stands as a representative high-point of the Lee-Kirby Thor run that would soon lead into the character's own numbered title.

Market data shows a large surviving population, with 478 Universal-graded copies recorded, and a price curve typical of a well-collected but non-key Silver Age issue: values stay compressed and modest through the low-to-mid grades before rising sharply above 9.0, and mid-grade demand has held fairly flat over the past year. The steep escalation between 9.2 and 9.4 sales, combined with the complete absence of any 9.6 sales or 9.8-and-up census population, indicates that top-end copies are scarce enough to command a significant premium whenever one surfaces, even without an established price point at the highest grades.

This is a book for Thor and Kirby-era Marvel completists rather than first-appearance speculators: demand centers on readers assembling a full run of the Lee-Kirby Journey Into Mystery/Thor saga, with mid-grade copies trading steadily as affordable additions to that run. High-grade examples, by contrast, are thin on the ground and would be expected to draw strong competitive bidding given the near-total absence of certified copies above 9.4, making a pristine slab of this issue a genuine outlier sale rather than a routine market transaction.
