old nails

[Moe (fl)]

Found these recently at the beach. They are 2" 1/4" inches long.

How old could they be?

Thanks.

Are they brass?

I dont see a smaller "pointed" end.

Here are some early 19th century bronze nails with washers. http://www.maritime-antiques.co.uk/30.html

And below that some that I found.

They are copper!

My guess is that they are from 19th century but would like to get other opinions.

Here is another pic.

Looks like shipwreck or flotsam.
