I would disagree that the GFC will double or triple the value of a high grade EC. It is much LESS common to find a high grade EC out there that isn't a GFC. There are quite a few Gaines copies out there as well, so yes, they are gorgeous copies, but I don't see a value bump in it being one. I'm not aware of any premium a Gaines copy brings, other than the high numeric grade they usually come with. In fact, I would argue it is one of the few pedigrees that does not carry a small bump in value. Just my 2 cents.
