Question on slabs

Well I am somewhat new to the slabbed coin world and I understand that coins in NGC black slabs are worth a “little” more.
My question is, are there other slab types that can add a premium to coins other then the possibility of an upgrade (PCGS or NGC).
Thank you for the help.

Black NGC slabs are generally worth a little more than a little premium, btw.

In some cases the holder adds the premium. For NGC it is the black holder. For PCGS the Regency and the doily.
