Graded at 7.0 (FN/VF) on 2026-11-02, from new photos taken out of the sleeve: front, close-up, back, spine and interior page. Small edge tear at the bottom with a short color-breaking crease, seen front and back. Tiny white fleck by the lower spine. Faint crease near a back corner. Top right corner slightly blunted. Cream pages with small nicks on the inner page edges.

Fantastic Four #103 arrived in October 1970 as the last issue to carry any Jack Kirby artwork on the title he co-created with Stan Lee. Kirby, departing Marvel for DC shortly after, provided layouts that were finished by Joe Sinnott, closing out one of comics' most consequential collaborations. The issue itself pits the team against the cosmic villain the Over-Mind, a lesser-known threat, but the real draw for collectors is the creative transition it represents, marking the end of the Lee-Kirby FF run that had defined the series since 1961.

Market data shows a book with steady but unspectacular demand across most grades, with FMVs holding in the low-to-mid twenties through grade 6.5 before climbing more sharply from 9.0 upward. That inflection point reflects typical Bronze Age grade-rarity dynamics: mid-grade copies are plentiful relative to demand, while high-grade copies become disproportionately scarce and desirable, particularly among Kirby completists and Fantastic Four run collectors assembling the Lee-Kirby era in top condition. No 9.8 has yet appeared on the census, underscoring how thin the population becomes at the summit.

This is a book that trades modestly in raw form and rewards patience at the high end. Low- and mid-grade copies serve reading and run-building collectors at accessible prices, while a 9.8 would command a strong premium as one of the finest known copies of Kirby's Marvel swan song. Long-term interest is likely to track broader Kirby and Silver-to-Bronze transition scholarship rather than any single character or story event.
