The overwhelming majority of high grade vintage cards are altered, without question. Marshal Fogel's entire collection, just about, has been trimmed or was cut from a sheet. His MBA black diamond 52T Mantle PSA 10 is almost certainly sheet cut. Same with Nat Turner's high grade vintage collection. Anyone swimming in those waters cannot avoid them. The submissions from the early days, in particular, at PSA were loaded with trimmers. They were the early adopters that helped to build the PSA brand. There's no such thing as a "truly" gem mint vintage card.
