I stopped at a friends tonight to return a tool I had borrowed, conversation ensured of course, and eventually the price of nails came up. Everyone uses nail guns and construction screws, and the old framing hammer and 4 inch nails technique is disappearing. Except for me of course, I'll drive a few nails in the small building projects I do... So he hauled out the remains of a 50 lb box of 4" nails and asked I wanted them. Trouble is; where would someone use 4" galvanized finishing nails?!
Also, note the poor quality control on the galvanizing process on the top nail.
