Personally, I've never used this (or cared at all about it).
I hadn't even thought of it in ages, until, I read Zing's post in the "Case of Lunar(s)" thread.
So...what do you other collectors here think of it?
Does anyone use it?
Will you buy a "graded" game for more than an obviously mint, factory-sealed version of the same game?
Seems to me (IMHO), to be a waste of time & money.
- thoughts?
