warshawlawI think David is right on the money vis a vis fake cards. An experienced collector will weed out 99% of them without much trouble.
I think there are more altered cards out there than fake cards per se, but far fewer than the card grading services want us to think. My experience has been that there are a considerable number of colored-in dark bordered cards out there, so I am very cautious on those. Also, anything in a PRO holder has to be considered altered.
