Unless they're female characters from Star Wars
. But even then the only female characters that sell like hotcakes are Princess Leia in a slave bikini or the ones based on the Expanded Universe(novels, video games, etc.), and then largely because they're EU figures and those always have much higher secondary market value than your average Luke, Qui-Gon or Rebel officer.
Being shortpacked or not carried forward in later waves and case assortments plays into that as well. Thinking it might be the only time you ever see that figure adds to the popularity.
