A lot of effort was put into making these as best quality production as possible.
An intending buyer does not need this sort of Mint product graded, because quality is already assured.
Same applies for current owners.
The comments about privy marks and impending change from current design don't mean much in terms of value, for NCLT with low mintage.
So no need to have it graded for little real benefit. If you do, there is a small worry about it being lost in shipping.
99.9% reliable is not 100% reliable.
It may well work out to just being an exercise in futility.
So follow the hype surrounding this issue, and pick out the small amount of real comment within the hype.
Oriole has made a very good comment that covers new issue NCLT in the numismatic after market. If you do decide to sell, timing is everything.
