Is there variation in XX Plasma labels? This looks different from the labels on the ones I've had.
Mine had a different style and font and the letter A before the serial, not W. Is this a label for a 2nd release of the XX Plasma?
Yeah it's a legit warranty label.
I saw that listing, seems a high price for just an inner box w/o outer sleeve and coin.
I suppose though it could be viewed as more valuable because it would make any unboxed pair more complete. A W box is like a wild card since (from my experience) W serial boxes didn't mateh the frame serials and often warranty frames weren't serialized.
