T206CollectorThere is a HUGE difference between a wet sheet transfer at the factory in 1909 and some guy running a ballpoint pen along the back of the card sometime between then and December 7, 2006. The first is a factory imperfection which, no doubt, impacts the grade -- just not at the SGC 40 or 50 level.
The pen mark is a drastic addition that ruins the grade. One of my nicest cards is a T206 Juan Violat, but the reverse has three huge purple symbols stamped on it -- an asterisk, an exclamation mark and something else I can't recall. The card would be an SGC 60 without the purple stamping. I just sent it in for grading and it should come back no better than an SGC 20.
