WORLD’S FINEST COMICS #143

Cover shows moderate wear consistent with a mid-grade Silver Age book: light corner rounding at top left and bottom corners, some surface scuffing and minor edge wear along the right edge, and a faint vertical crease near the left margin. Colors remain bright with no major color breaks, fading, or staining visible, and there are no major tears. The book is in a protective sleeve, and the interior/back cover were not assessed.

World's Finest Comics #143 (DC, August 1964) continues the Superman-Batman team-up format the series settled into during the early 1960s, bringing back the Composite Superman, the powers-amalgam villain introduced the previous issue. Curt Swan supplied the cover and interior pencils, with the era's regular World's Finest creative team of Edmond Hamilton on scripts and inkers rounding out a story built around the character's return engagement rather than his debut. The book is representative of the tightly plotted, gimmick-driven Superman/Batman pairings that defined the title through the mid-1960s, with the Legion of Super-Heroes' powers backstory giving the villain his hook.

Market data shows a shallow, steady price curve across mid and high grades, with only modest separation between 6.5 and 9.2 copies and thin sales volume at every point on the census. There is no certified 9.8 on record, and even 9.6 copies are scarce, which points to a book that simply does not turn up often in top condition rather than one facing active competition for a pristine copy. Demand is driven by Superman/Batman team-up completists and World's Finest run-builders rather than by first-appearance chasers, since the Composite Superman's debut sits in the prior issue.

This is a mid-tier Silver Age DC book: readily available in worn condition for run-fillers, modestly priced in mid-grade for collectors upgrading a World's Finest set, and commanding a real but not dramatic premium in the rare high-grade slab given how few copies have been graded at all. It suits collectors assembling complete World's Finest or Composite Superman story arcs rather than speculators seeking a breakout key.
