Yea that card in an open auction or even with a higher BIN easily sells for close to $1000. These shields, and the dual ones out of The Cup are where a lot of people with deep pockets make made money because every so often you get small time sellers who underestimate the market and think "oh $500 or $1000 is a lot of money for a card, I'll take it", yet a lot of the time they are getting substantially less than they could.

Hopefully the guy who got it is a hard core Vanek collector, otherwise I would not be shocked to see it re-listed in a week or two at around 1200-1500 BIN/BO.
