Please understand that the following is ebay's opinion of you and all sellers. It is not my opinion of you or any seller on ebay.
You are wrong. You are a seller, you have no rights, or appeals process on ebay. ebay does not care who you are, or what you have done, or how you can prove it beyond a reasonable doubt. The buyer is the jury and ebay is the executioner. If the curator of the Smithsonian says something is real and the buyer says it is not, ebay will listen the the buyer and charge the Smithsonian for original and return shipping and take another 4% of their gross sales in the future for being a bad seller compared to their peers. You are wrong and always will be.
You are a seller-you are wrong.
You are a seller- you don't know anything.
You are a seller-ebay does not care about you.
You are a seller-you don't know how to manage your business.

You are a seller-you don't know how to price anything right.
You are a seller-you don't know anything about customer service.
