Probably worth mentioning that PSA has not done a great job segregating the series variations in this set. Initially there was no "NOF" differentiation, so no doubt some of the early pop counts will contain both. Also, PSA has a separate 1910 pop report for 2nd Edition cards. I have no idea if this is still active.
