Fantastic Four #166 (January 1976) arrived at the tail end of Roy Thomas's run scripting Marvel's flagship team title, with art by Rich Buckler and inks by Joe Sinnott completing the multi-issue Sphinx arc that had begun a few issues earlier. The story pits Reed Richards, Sue Storm, Johnny Storm, and Ben Grimm against Anath-Na Mut, the ancient Egyptian sorcerer known as the Sphinx, whose power derives from a Cosmic Cube fragment known as the Ka Stone. The issue is a solid example of mid-1970s Marvel cosmic-adventure storytelling, blending pseudo-mythological villainy with the interpersonal dynamics that defined the Lee-Kirby foundation Thomas and Buckler were building upon.

The book's market profile reflects its status as a well-collected but non-key chapter in a long-running, heavily preserved series: a substantial certified population (nearly 400 CGC Universal copies) keeps supply ample across the grade spectrum, and sales activity is steady but unspectacular in the mid grades. Demand is driven primarily by Fantastic Four series completists and Bronze Age Marvel collectors assembling the Thomas/Buckler run rather than by any first-appearance or landmark-event premium, which keeps raw and low-grade values modest while high-grade certified copies still command a real premium reflecting the difficulty of finding pristine surviving copies from ordinary newsstand distribution.

This issue trades as a dependable but unglamorous run-filler: budget-minded collectors and dealers restocking longbox inventory will find raw copies in low and mid grade readily available and inexpensively priced, while the 9.8 tier draws a narrower pool of grade-focused Fantastic Four specialists and registry builders willing to pay a steep multiple over mid-grade value for top-census condition. It is best positioned in inventory as a complementary piece to the surrounding Sphinx-arc issues rather than as a standalone highlight.
