JohnPlank my guess would be around 70-80. 150 series are the better cards (Clear & Crisp) of the bunch most of the 350 series seem fuzzy or out of focus. Maybe as time went on the plate really did wear down hence the short print.
The best looking Plank I have seen for sale besides the Harris/Copeland PSA 7 was a PSA 3 SCP sold a few years back, really great image.
