Red Cobb survey of all its 30 backs....post your inputs ?

[camlov2]

I have seen a handful of threads regarding certain cards and their backs....

one question, Does it make sense to count cards that the owner no longer has?
Couldn't these cards have been passed to another Net54 member and be counted twice?

I am new to the boards so I don't know how much turnover there might be within the group.
