Here is the
PSA pop. report for the E98 set.
It does appear as if there may be a [small] number of additional cards out there, but the auction description does mention that there are two PSA 10 Kling's for example.
Notably, the Pop. report has many examples of a few cards:
Twelve Chief Meyers graded PSA 9 (and two graded PSA 10)
Eighteen Johnny Kling cards graded PSA 9
FIFTEEN TY COBB cards graded PSA 9.
Those numbers for those three players are even more extreme than the Toleteros Gibson. At this point, only a fool would pay up significant coin for one of the Cobbs.
