FANTASTIC FOUR #23

Cover shows notable wear including a vertical crease/soft spine roll on the left edge, spine ticks and slight fraying at top and bottom of spine, and a corner tear/wear at the upper left tip. Color is bright with no major fading, but there are small edge nicks along the top and right border and light surface soiling. Interior and back cover were not assessed from this photo, so overall grade could shift once those are examined.

Fantastic Four #23 (February 1964) pits the team against an alliance of two of Marvel's most enduring antagonists, Doctor Doom and Namor the Sub-Mariner, in a story scripted by Stan Lee with pencils by Jack Kirby and inks generally attributed to Chic Stone, who had recently taken over inking duties on the title. The issue arrives during the sustained early-1960s run widely credited with establishing the dramatic template of Marvel's superhero line, and it showcases Kirby at the height of his Silver Age design work on both villains, whose recurring pairings with the FF became a signature story engine for the series through the 1960s.

Market demand for the issue tracks the broader collector appetite for early Fantastic Four issues featuring Doctor Doom and Namor rather than any first-appearance premium, since both characters had already debuted earlier in the run. Certified population is substantial, with over 860 universal copies on census, and sales activity is consistent across the mid and high grades, producing a smooth, steadily rising FMV curve from the low grades up through 9.4. The near-total absence of certified copies above 9.6, and only a single 9.8 on census, concentrates value sharply at the top of the grade spectrum while leaving the bulk of the population, and most trading activity, in the 6.0-to-9.0 range.

The book suits collectors building a complete run of early Fantastic Four issues or a Doctor Doom or Sub-Mariner character collection rather than buyers chasing a marquee key. Raw copies in low and mid grade trade as affordable, accessible pieces of the Lee-Kirby FF run, while high-grade certified examples become scarce quickly above 9.0 and the single known 9.8 would represent a condition-census event rather than a routine sale. Long-term demand should remain steady, anchored by the title's foundational status in the Marvel Universe and the consistent presence of Doom and Namor in modern media and comics continuity.
