A few months ago I bought a Kane mask on ebay. It was a mask that he supposedly wore in the ring, and wrestled in. It looks authentic, and I never doubted that it was real but now i have video proof of it. He wore it at an event called the Survivor Series in 2000. How do I go about getting a Certificate of Authenticity for it? That is the only thing it's lacking. Without a COA it's really worthless. How would I go about getting one?
