The galleries on the T206 Resource show 46 Wagners and 64 Planks. There are almost certainly more of each out there, but given the status of these cards in the hobby and the amount of time that people have been following them, it seems to me that the ratio between these might at least be close.
I can make an argument for a slightly larger % of unknown Planks than unknown/not in the gallery Wagners. The Resource ratio is 64/46 Plank/Wagner, or 1.39:1. If we bump this up to assume a few more missing Planks than Wagners, say 1.5:1 and go with 60 Wagners, that gets us to 90 Planks.
I think a more interesting question for Plank is how many 150 vs 350 there are given how much nicer and more desirable the 150s are. At the moment, I think we know the backs of 51 Planks:
SC150/25 - 2
SC150/30 - 9
PD150 - 5
SC350/30 - 35
16/51 (31.4%) of these are 150 series. Applying this to the total of 90 above, that means we have 28 of the 150s and 62 of the 350s.
