Those are not nails they do not go in point first that is why the point is not sharp . They are storm anchors for asbestos roof tiles ,used to hold down the bottom edge from wind lift . the flat part goes against roof with pin sticking up between two tiles ,the next tile has a pre drilled hole at bottom edge the pin goes through and is bent over.

A few months ago, I got permission to hunt around a very old building, that I KNEW was going to produce some nice silver coins. In a 10 x 10 foot area, I probably dug 20 of those things !! They are EVIL !!

They are worth their weight in copper....($3.61/lb.).... I carry a bucket in the truck just for the copper and brass finds. It adds up pretty fast.
