// Archive commentary

John Carter, Warlord of Mars #9 continues Marvel's late-1970s adaptation of Edgar Rice Burroughs' Barsoom saga, with Marv Wolfman scripting the interplanetary adventures of John Carter, Dejah Thoris, Tars Tarkas, and Kantos Kan. Gil Kane's pencils, inked by Rudy Nebres, bring a dynamic sword-and-planet energy to the title, reflecting Marvel's mid-decade push into licensed adventure properties beyond its core superhero line.

The series has never generated strong collector demand, and this issue is no exception: certified sales are scarce across the grading spectrum, with only a handful of transactions recorded even at the higher end of the census. Pricing stays modest from raw copies through the low double digits at mid-grade, with only a slight uptick at the top of the certified population, indicating a book acquired mainly by Burroughs completists, John Carter fans, and Gil Kane art collectors rather than speculative investors.

This is a fringe title in the broader Bronze Age market, appealing to a narrow but consistent base of licensed-property and Kane/Nebres art enthusiasts. Raw copies in low and mid grades trade for nominal sums reflecting general availability, while high-grade certified examples command a modest premium purely on condition scarcity rather than character or story significance. Collectors seeking Barsoom material or complete Wolfman scripting runs represent the primary market for this issue.
