Key issues
Harley Quinn's first comic is The Batman Adventures #12, cover-dated September 1993 from DC Comics. It was printed in large numbers, so its price depends mostly on grade: 9.8 copies, newsstand copies and the scarcer second printing carry the premium.

Key issues
Most famous Batman quotes come from films, TV and animation rather than the original comics, and no quote makes a comic more valuable. What collectors pay for is a key issue, such as Detective Comics #27, in a high certified grade.
