LOL. Way too funny. From my search, there is no such thing as an TOY AUTHORITY GRADING (T.A.G.).
The figure is graded by them & a T.A.G. grading sticker which was made of a home printer, is attached inside a Star Case. Don't forget, they are also a Third Party Experts.

Nothing but a selling gimmick. This seller gets my all time Garbage Award.
