amphora...

hi I´am new here. And I´m not a archologist. Last year, a friend and I found on several dives amphores. We went to the museum to find some infos about it and if it is true the rage is from 300 bc to 400 ac. In the pic you can see some pieces! Is it forbiden to sell this stuff? Is it worth something? thanks for helping Anhang gelöscht Sebastian
