QUAVIET

Ladies and Sirs, I have two short questions I am submitting. 1.) If I submit a NGC MS66 coin to PCGS for certification and the coin is graded by PCGS at MS65, does PCGS inform me of the lower grading and let me have my NGC coin back in it holder at MS66, of course I expect to pay a fee. 2.) I have noticed at Heritage auctions that some PCGS coins "past winning bids" equal NGC and some coins sell for 50% to 100% over NGC winning bids. Is this because collectors are bidding up the PCGS prices due to their competition or is this because of a basic flaw of NGC grading. I have posted this site before and received informitive answers. That is where I learned about collectors competitions. It's just that on some coins that the price difference for a coin in equal grade and physical appearance between PCGS and NGC is very great. This leads me to believe that there is a fatal flaw with NGC grading or that NGC is the best buy for quality. Thanks Robert
