WORLD’S FINEST COMICS #139

Cover shows good gloss with strong color on the red/yellow logo and black background, though there is noticeable wear at the spine with several small ticks and a bit of fraying visible along the left edge binding. Corners appear slightly blunted rather than sharp, and there's minor surface wrinkling near the top edge. The book is in a protective sleeve, and interior pages and back cover were not assessed. No major tears, creases, or color-breaking folds are visible in this image, but the overall wear pattern suggests a mid-grade copy.

World's Finest Comics #139 arrived in February 1964 during DC's long-running Superman/Batman team-up era, a period when the title paired the company's two flagship heroes in a lead story while rotating a secondary feature — here, Green Arrow — through the back pages. The era's creative mainstays, writer Edmond Hamilton and penciler Jim Mooney on the lead feature, with George Papp handling Green Arrow, produced a reliable but unspectacular run of adventure stories aimed at DC's core readership rather than at introducing new characters or concepts.

The certified population is modest at 44 Universal copies against 47 total graded, with sales concentrated in the mid grades (6.0 through 7.5) where most of the recorded activity and pricing data sits. Values climb sharply above 9.0, with a single 9.6 sale trio establishing a $1,700 benchmark, while the two 9.8 census copies have yet to see a public sale — a pattern typical of low-population Silver Age issues where top-grade rarity outpaces documented demand. There is no first appearance, death, or landmark creative event tied to this issue, so its market behaves as a straightforward supply-and-condition play rather than one driven by character milestones.

This is a book for Silver Age DC completists and World's Finest run-builders rather than character-key hunters. Lower and mid-grade copies trade in the range of a casual back-issue purchase, while the jump to near-mint and gem-mint certified copies reflects raw scarcity at the top of the census rather than any content-driven premium. Collectors assembling a complete Superman/Batman team-up run will find this a steady, if unremarkable, addition, with pricing likely to track census growth and any future 9.8 sale rather than any shift in character demand.
