I was pleasantly surprised when they game back with a proof grade. Also, objectively, the appearance grade on these coins should higher, but ANACS is not really sure how to account for the hologram.
If you're serious about wanting a platinum coin, I have a list of interested parties. We're only going to produce enough of them to cover that list, and I don't intend to make them available publicly.
I always buy them from a friend who is most likely already on that list! I will hit him up for the platinum edition. Will it be the same design as the gold or something new and special?
The platinum coins are a new design. Bitcoin will soon have a lady mascot.
