steve kBen - Very sorry for your loss. I will completely agree with some posters here that someone definitely knew the cards were there and very probably also knew you were out of the apartment. You mentioned that "at least none of my family was hurt" and you are of course right about that. But if you have children, especially teenagers, one of their friends/acquaintances could have easily had something to do with this. Kids normally have big mouths and one of your kids could have mentioned your valuable collection to someone. I have known people in which this exact scenario happened whereby the persons son's friend, knowing the collection was there and knowing that the family would be out of the apartment - broke in and stole it.
Very best of luck in hopefully getting your cards back.
