this is what they are asking me for:
please
obtain a document from an unbiased, third-party, such as a dealer,
appraiser, or an organization that is qualified in the area of the item in
question (other than yourself), which clearly identifies the item as not
authentic. The document must specifically state how the item received
differs from an authentic item and must include a detailed explanation of
how the person evaluating the item determined that it is not authentic.
