All cards are graded using the high standards specified by each grading company. Every crease, trace of residue, and sign of wear (or lack thereof) is scrutinized before a final grade is assigned to the card. Even the tiniest detail matters. Each grade is based on four attributes of the card consisting of corners, edges, surface and centering. In the event the card is autographed, then that too is considered in the grading process making a fifth attribute graded. With each grade a guarantee of authenticity is attached ensuring that every card is exactly the card it says it is. This allows buyers to be able to enjoy every card knowing the card they purchased is exactly what they paid for.
