>>>I consider that a slab. Though they are not graded based on condition, they are graded as "Authentic" .

(Newbie opinion alert)

I don't.

Slabbing is the attempt to assign a "grade" to a chip (thus set a value). The fact that it is in a container (whether sealed or not) does not constitute a "slabbed" chip.

"Authentic" IMO is not a grade.
