I cleaned this piece a bit today with washing soda, aluminum foil, boiling water method and it removed all the green patina. The piece now looks dark brown and you can see some copper spots. The most interesting find is that I can see a date now of 1715 or 1719 or 1745. I am not sure about the third number but the others are pretty clear. Also the 'R' could be a 'B'. The piece was found in Florida.
