OB is valid in Collins, not in North America — 4 points
It depends on the list you play by. OB is in Collins, used in the UK and most of the world, but it is not in the North American lists — so in a US or Canadian game an opponent can challenge it off the board. Worth 4 points. Words with Friends does not accept it either.
