Hundreds of them. Intact with all mortar removed.
I don't know how many there are, but that stack is four bricks thick.
I will only consider gifting them to someone who is going to 1) take ALL of the bricks and 2) cart them out of my backyard without my help. If nobody wants to do that, I'll just keep them.
