Grading requires mature judgment. That is why all PRO graded cards are graded by two experts, and a copy of the grading slip is returned with each card PRO grades. Another copy is kept on file, if a purchaser in the future wants to check on why the card was graded a 9.5 instead of a 10. A small charge may be made for this service, but it could be very important to someone considering a $10,000 bid on E-Bay.
