barrysloateBruce is right on the money (are you amazed I am so agreeable?)
Pre- 1915 cards are quite difficult to find in PSA 8, save perhaps T206 and Cracker Jack where sharp examples have survived.
But the majority of sets from 1887-1915 probably have a miniscule survival rate in NR MT/MT condition. That's why if you love 8's you are forced to collect what's out there, and it mostly ranges from Goudeys to the present.
