Yeah, “fake” has been shouted about the Phaistos Disk, the Minoan “snake goddess”, the treasure from Troy. The Nefertiti bust has been Xrayed or somethin’ (possibly a link up above) showing it had been carved first, then more artfully plastered and painted. There was a German guy I think, who claimed it was a classic fake because one of the eye insets was missing and never found in the sift at the site. I suppose he’d say the same thing if neither inset, or both insets, were present. :^)
And the Lady of Elche, which actually does look a little too contemporary (1890's) to be true.
