Eric BrehmTo get back to the original poster, I have never seen a card that actually made me vomit, although I have seen some with enough ugly stains, creases, or pieces missing to cause me to gag briefly.
Seriously, Scot Reader has done some rough estimates of the total number of T206's that were originally produced, and the number that have likely survived to the present day. (I don't have access to his study where I am right now, away from home.) His estimate could be used as a denominator to estimate the percent that have survived in high grade (assuming that most of the higher grade ones have been holdered by now).
