What is anything about these (http://www.forumancientcoins.com/gallery/displayimage.php?album=2709&pos=0
copper (or bronze) nails. These nails were found in an ancient shipwreck, just off the cost of Caesarea. It looks just about as old as you can find in Caesarea, so it seems to be ~2000 Yrs old.
Thanks in advance,
