I submitted these Lee Seung-yeop raw cards back in August to PSA when I was visitng my family in the States. I submitted these along with other Don Mattingly and Mark Buehrle cards. I think I got a grader on a good day. I couldn't believe all but one of the Lee's came back as GEM MINT 10.
These are from a promo set but what I didn't realize was that two of the three are unnumbered and the third is numbered #80, which might be a mistake (don't have the cards on-hand).
