Water Pitcher

Hi, I am tryng to get some idea of what this is worth. The history of this item is the following :It was excavated in GAZA. It was given to my mother as a gift on the occasion of her launching a ship in Islreal. My dad was in the navy and he built ships. The original document of authenticity was unfortunately lost over the years but some dealers have suggested its over 2000 years old.
