Answer 1

Post the pictures somewhere so we can see. Also, maybe look on eBay.
I have a bunch of old bottles I found years ago, they are about 130 years old (they have dates on them). Last time I looked, they were worth about $10 each.

Where were your snorkeling, in the Merrimack River? That's pretty cool that you found the bottles.
