I think it would depend on the year/card etc. in determining if it was fake. I forgot the exact website but I found it through this forum, but anyway they did a complete breakdown on fakes of iconic cards (52 mantle etc... and other cards) and gave a general breakdown as well. I'm sure someone on this forum will have the specifics.
PC Players: Alex Bregman and Christian Yelich. Looking for any and every I don't have.
