Last time I checked, "mint" meant original gum, and "NGAI" meant No Gum As Issued.
So how can this stamp, which is very clearly used, be described with both of these terms?
You'd figure that it would be one or the other, but it's actually neither.
Seeing as how these stamps were, in fact, issued with gum, of course.
