    Batman Adventures #12 explained: Harley Quinn's first comic appearance

    The Batman Adventures #12 (September 1993) is Harley Quinn's first appearance in comics, a year after her television debut in Batman: The Animated Series. It is the most valuable comic of the 1990s after New Mutants #98 and a standard Modern Age key. Because it was printed in large numbers, the value sits almost entirely in 9.8 copies, newsstand copies and the scarcer second printing.
