If you have to ask if that POS Mantle is real or fake then you're way over your head in trying to buy raw cards. Stick only to graded cards by PSA and SGC offered by good sellers. And to answer the next inevitable question, those Craigslist graded cards you'll be offered at 20 cents on the dollar aren't the real deal.

A PSA 7OC recently sold for $218!
Personally, I'd rather have a nicely centered PSA 6.
