Yes. It's the same as the price difference between anything that is new vs used.

I personally would pay a premium to have that extra piece of sticky tape, but that's just me.

MIB and loose (with the exception of vintage stuff like G1) should have no price difference and are the same in my eyes (provided both figures are of equal condition).
