IIRC there were only 5 ''#9'' cards originally, created by a restorer in SoCal, Jamie Hernandez possibly (but don't quote me). He use to advertise them in Movie Collector's World. At the 2nd Famous Monsters Convention in LA in what, 1992 or 93, he was selling all five for 100 bucks. They were limited to 200 each I think. I also believe that the WotW was not part of the original deal but came later from some one else (again, no quotes). The flood of new "#9" cards started a few years back as digital got better* and closer to the original reproductions were possible^.
But the seller is a loon, that you may quote me on.
