I know this is a fake, I sent the seller an email and his reply:
"Who the hell are you and who asked you your opinion..anyways I took it in into a reputable store and was told it was truly authentic ..you moron."
Notice how the back scan has a chunk missing but the front doesn't...kinda reminds me of the movie Dumb and Dumber.
