Considering all the rip offs online,,everyone should be pessimistic !! I look at everything as a fake until I prove that it isn`t !!
What do you think would happen if you sold something as an original and the buyer found out that it wasn`t ?? That comes back to bite you in the butt and its your reputation that is at stake !!
I hope she is right but for her own benefit she needs to be sure !! Whatever amount she sells it for may not be so easy to give back !!
