Sounds like we could all do a better job grading crypto coins than most of these services.

But let's be honest about the range of variation in these coins. Except for the 2011 brass, the rest that are being offered for sale have NEVER been circulated, never sat unprotected in a desk drawer or in jeans pockets. They're all "from Mike's hands to yours" uncirculated mint condition.
The only criteria that can has variation to grade upon is the alignment of the first bits, the quality of the hologram, the alignment of the hologram to the obverse side
BTC. Scuffs and condition of metal should also fall in this category but since these aren't circulated there are zero variation on the metal among coins.
So, to your point...are we the suckers for sending ANACS "the same" coins and believing in their varied grades?
If anything it makes ANACS choice to assign this coin as a 70 even more rare.
