I can tell you with 100% confidence that everything, except perhaps for the Nickel Three Cent pieces, is fake. They are probably bad too, but the pictures are so small that it is hard to tell for sure.

That leaves the 1884 three cent which appears to be the famous "fallen 4" variety, which is well known for 1794 large cents, but no so popular among the three cent pieces.
