Does anyone reconize this style of bronze chain

I found this chain off the east coats of Florida and i am curious if it may be from the 1715 fleets, i have searched the internet a little with no luck and have no clue what it is. looks like it has a symbol of a sun on it.

What size is the chain? And can you get a better pic of the symbol of the sun?
