Funny, I never noticed that before when I had the foil. Huh.
There are quite a few mistakes like that, where there were entire runs that had misprints, and Decipher didn't do anything about it. There was a Celeborn (Lord of the Galadrim, methinks?) that had the wrong number on it. It drove me crazy when I was selling my cards because I had to show the number the card was meant to be and the number that was actually printed on the card in the title, then explain this in the item description.
It didn't seem to make much of a difference to the people bidding on it, though. I think that those who know LotR cards know that these things happen from time to time.
