Need Help Identifying Bottles!

[rgecy]

I have attached some pictures of a couple bottles I found on a dive back in January.? The bottles look Black but are actually very Dark Green when you hold them up to the light.? They measure 9-1/2" tall.? If you can see it in the pictures, there is a horizontal seem across the shoulder and a vertical one running up the neck.? The pontile also has some letters, (and possibly a number).? If you look close you can see the letter "K" on the right side of the pontile.? On the left, I think is the number "4".? The other bottle has a "D" and maybe a "1" on the bottom.

From what I could find, I think they are from the early 1800's! (But have been told they could date to late 1700's)
What do you guys think?? Any idea on Price?? Any specifics on where they might have come from?

Thanks,

Your bottles appear to be three piece mold.? Three piece molds where made from early 1800s until 1889.? I am guessing they are either mineral water, soda or beer bottles.? Price?? I am saying around $7.00 to $15.00 a each depending on color and condition.
