Thieves hit a Wisconsin card shop for $340,000

Four masked guys cleaned out Goldenrod City Collectibles in Twin Lakes, Wisconsin in just over six minutes.
They took at least $340,000, a lot of it graded Pokemon.
Police got there ten seconds after they left.
The Battlegrounds in Dalton, Tennessee lost about $14,000 in One Piece slabs and boxes.
Punch-Out Games in Minnesota lost $30,000 to $50,000 in about a minute and a half.

Are graded slabs sitting in open display cases just asking for it now, or do you lose more sales hiding them than you'd ever lose to a break in?
