Beautiful Antique Middle Eastern Egyptian 900 Silver Tray Inscribed

I was only able to figure out this small amount about this plate. Thank you so much for looking and I hope you enjoy the piece. From 1966 the "lotus" marks have been replaced by the. Lotus with dots on the sides. Corresponding dots were added to the date letters. According to a source, when the war between Egypt and Israel occurred in 1967, Egypt stopped until 1974 importing from England the steel pens used to trace hallmarks on jewelry in order to conserve their reserves of foreign currency.
