BobSamuel- I don't think it is the authenticity of cards here in question but rather whether a real card was altered and the other 99% of the items questioned are not cards but memorabilia, like signed balls and bats and whether uniforms are real, etc.
I personally don't collect any signed memorabilia unless I witness the signor actually signing it because of the fakes out there, even fakes which have been "authenticated" by supposedly knowledgable third party "experts."
There are fake cards floating around but 99.9% of those can be spotted by conscientious collectors who do their homework.
