Not sure how accurate this is
Only three Ty Cobbs have been graded: one is graded PSA GOOD 2, and two examples (including this one) are graded SGC GOOD 30. Incredibly, the T214 Victory Ty Cobb is even rarer than suggested by these modest population report numbers, as the three graded examples represent only two different cards. (It is our understanding that many years ago the PSA GOOD 2 example was crossed over to an SGC GOOD 30 holder, and the old PSA label was never returned to correct the pop report).
