BrianAfter the last guy posted a T206 fake cobb on the board and then listed it on Ebay.....not sure if I should answer this or not 
The fail safe way for me is to have a 30X loupe (buy them for $5 on ebay) and compare the questionable T206 with a GAI, PSA or SGC slabbed T206. Pick up a slabbed poor condition T206 for less than $20 and use it for your comparison. The printing dots will either look the same or different as the slabbed one.
