Re: Strange 9mm case
That's a great lesson. First thing to look for in fired cases is whether it's BOXER (single flash hole = reloadable) or BERDAN (two or more flash holes = not really reloadable). Most European brass is Berdan primed, while we use mostly Boxer cases in the U.S.
Not to say it isn't reloadable, but need special tools and special primers. Some U.S. makers do produce non-reloadable cases. As you say, some are aluminum. Toss those right away. I'd toss any steel cases, too.
