GODZILLA #21

Cover shows strong gloss and sharp corners with no visible creasing or color breaks; spine appears tight with no stress ticks visible in this photo. The book is in a protective sleeve which limits full assessment of edges and surface. No fading, staining, or writing is visible on the front cover. Interior pages and back cover were not assessed, so grade is based solely on this front-cover image.

Godzilla #21 belongs to Marvel's short-lived license series chronicling the giant monster's rampage through the Marvel Universe, here scripted by Doug Moench with art by Herb Trimpe and inks by Dan Green. The issue is notable chiefly for its crossover conceit, bringing Godzilla into contact with Jack Kirby's then-new Devil Dinosaur and Moon Boy alongside guest appearances from the Fantastic Four's Human Torch and Invisible Woman, plus S.H.I.E.L.D. regulars Dum Dum Dugan, Gabriel Jones, and Jimmy Woo. No characters debut here, and the issue carries no origin, death, or other landmark event; its interest is rooted entirely in the novelty of the team-up rather than any first appearance.

Market data shows a typical Bronze Age curve for a book that was not heavily hoarded in high grade: modest, steady demand at the top of the census with values climbing sharply only from 9.4 upward, while sub-9.0 raw copies trade for a few dollars reflecting ample surviving supply and limited grade-driven urgency. Sales volume at 9.8 is meaningful relative to the size of the census, suggesting active collector interest in top-tier copies specifically, likely driven by Godzilla collectors and Kirby-adjacent Devil Dinosaur completists rather than mainstream Marvel key-issue buyers.

This is a solid mid-run crossover issue for specialists rather than a broad key, and it collects primarily among Godzilla-license completists, Devil Dinosaur and Moon Boy collectors, and Bronze Age Marvel crossover enthusiasts. Raw copies in low and mid grades remain inexpensive and plentiful, while the market rewards well-preserved 9.6 and 9.8 slabs disproportionately, making this a book where grade, more than rarity of the issue itself, drives most of the price differential.
