Civil war period tin type i.d. help!!

[nikonshooter]

These are some, from what i can find, civil war period "tin type" photos. I was wondering if anyone might have seen one or know any solid info on any of them. Short of that, any leads on any decent ways of solidly identifying them would be much appreciated.

Sorry for all the URL's
