This is an incredibly rare figure, but hundreds of people own one if you go on the FB sites. Either it's not rare at all, or loads of people that believe they have a genuine one have been duped into buying it.
I honestly wouldn't trust anyone's opinion on this other than Ozio's (Horacio Narvaez). Others like Marco Jay (Dr Dengar) or Wolff's (Wbobafett) might be pretty good, but really Ozio is the man when it comes to Ledy.
He would have a good idea if it's an obvious fake, but if it's a good fake he may need it in hand.
