I can tell you that the grading process is extremely picky. The smallest detail is wrong and the card goes from high end value, all the way to worthless. Even something that you cannot control, like the picture not being perfectly centered, it hurts the value of the card tremendously. Having your cards graded can get really expensive as well.
I'll try to post a better explanation of it all soon.
Yes doctor, I am sick.
Sick of those who are spineless.
Sick of those who feel self-entitled.
Sick of those who are hypocrites.
Yes doctor, an army is forming.
Yes doctor, there will be a war.
Yes doctor, there will be blood.....
