Mithrandir,
That's a very nice 5c. error coin that you've got there.I'm surprised that you found it on the extremely controversial auction website that is eBay (which I call FleaBay,as it is like an 800 lb. gorilla that has parasites in the form of scammers).
Be extremely careful who you deal with up on FleaBay,as FleaBay are trying to force all their members to accept only PayPal as an 'acceptable' payment method.
