I must be getting old but I just don't get it. It says MS68. What the hell does that mean? It's a shiny disk, but it's not currency (as we know it Jim). Why does it need grading? If they wanted they could just say 'Genuine' but I feel that the whole grading-things-that-don't-merit-grading just makes the TPGS thing even more ridiculous than it already was.
I can see the point in things that might circulate. Like trading cards, banknotes or comics. But this is like grading the box the trading cards come in! The metal disk has no significance beyond what it holds .. except perhaps to a museum as a curiosity. It's just daft IMHO. Or maybe it's just me?
