I have been given a partial list of the pins and numbers made by Planet by a former ex-worker.  I have some of these pins but was never really collected Image or Valiant Comics, so my knowledge of who some of these characters are is limited.  Also I've noticed there is a Marvel pin listed - FFb-1A Invisible Woman,  so the list is a bit mixed up.  But it's all I have at present, and it does add some more pins to Planet Studios.
