This Chinese Mew EX 88/92 from EX Legend Maker is the highest grades BGS copy of this card and there is one 1 in existence. Yes, this is a population 1 card. See the pictures of the BGS Pop report to confirm.

That means unfortunately there are zero comps on this card and it is for Mew collectors or collectors of rare cards. You will probably never see another!

Guard not included.
