TALES TO ASTONISH #100

Cover shows moderate wear typical of a Silver Age book: soft corners, some edge wear along the right edge, and light overall toning/yellowing to the white cover stock. There is visible surface rub and a few small creases near the spine but no major color breaks or tears visible; the book is in a protective sleeve which limits full assessment of edges. Interior pages and back cover were not visible and were not assessed.

Tales to Astonish #100 closed out the dual-feature era of the title, arriving as an oversized anniversary issue that recapped the parallel careers of the Incredible Hulk and Prince Namor, the Sub-Mariner, before both characters graduated to solo books beginning with issue #101. The issue's retrospective format, pairing new story pages with a look back at each hero's development, was Marvel's way of marking the transition, and it stands as the connective tissue between the shared-title Silver Age format and the sustained solo Hulk and Sub-Mariner runs that followed through the late 1960s and beyond.

Demand for the book tracks its role as a notable transitional issue rather than any first appearance or origin story, and the certified population reflects that: a large census of over 800 Universal copies with steady sales activity across nearly every grade. Pricing rises sharply at the top of the curve, with a wide gap between the mid-grade tier and the 9.8 tier, typical of a book that is plentiful in mid and high grades but scarce in true gem condition. The thirteen 9.8 copies on record command a substantial premium over the next grade down, indicating collectors will pay up disproportionately for top-of-census examples even absent a landmark key status.

The book suits Silver Age Marvel run-builders and Hulk or Sub-Mariner completists rather than speculative key-issue buyers. Raw copies in low and mid grade trade as affordable filler for readers assembling the title's full run, while high-grade certified examples, especially 9.6 and 9.8, draw stronger competition from collectors chasing condition census status on a book whose surviving gem copies are comparatively few. Long-term interest is steady rather than speculative, anchored in the issue's historical role as the last chapter of the original Tales to Astonish before the characters' titles diverged.
