I got an expert opinion that the card was fine, so I waited until the auction ended earlier tonight before posting anything. And the auction did really well (about $135 more than the recent PWCC auction for the card in the same grade):

My concern was with the size of the card relative to the holder (lots of extra room). I feel like I've been seeing more Chicles that look small recently. Often they are placed in a larger holder with a mylar over them. I guess I've been really paranoid after reading the 48 Leaf thread we had a while back about all the trimmed cards winding up in graded holders....
