While diving in the Bahamas I found some cannon dated 1560. These bottles were nearby in the sand, and may not be associated with the cannon at all.
The first two are green glass with bubbles, and are irregularly shaped. There are no markings on the sides. The first is 25cm tall.



The second is 27cm tall:




The third is clear glass with a really cool spider's web imprint, including the spider! 26cm tall.



I'm guessing the first two are the oldest, and are gin bottles, and that the third is a fairly modern rum bottle.
What do y'all think?
