Just wait when it comes time to sell and you (or God forbid your heirs) mosey on down to the local coin show and face the inevitable "well, PCGS just made a mistake on THAT coin as it's overgraded!" and will try to get you (or your heirs) to part with it for XF/AU money. (Yeah... A huge spread exists between AU and 62 and some in the coin dealer fraternity will use it to their advantage every chance they get)
Some coin dealers can really stink up the place sometime with their opinions and offers.
You gotcha a nice coin and a nice accurate grade to go along with it! Congrats!
