A nail - life stages

After I finished tearing our old deck down I recovered a few of the nails.  The nails are about 20 years old; the picture shows what should be the same style nail in different stages of decay.  They appear to be some type of (lightly) galvanized spiral shank nail.  As I rebuild our deck, I hope that the newer "triple hot dipped" type connectors and fasteners hold up better - and the other "coated" screws as well.

If you are wondering about the odd looking protrusions near the head, tip, etc of the nail - I picked up the nails with a magnetic sweep and it left them mildly magnetic. The nails retained small bits of rust from the sweep which are like iron particles following the magnetic field lines.
