The rectangular plaque, with curved edges is inscribed with a dedication engraved in Hebrew square letters, which reads:
"'(אל) שדי'/ הקדש/ ק"ק גד/ וש (גדול) יב"ץ (יראה בנחמת ציון; ברכת המזון) מה/ יקר הר' יום/ טוב עטיאס/ הי"ו (ה' יחיהו וישמרהו)."
"'(El) Shadai' (God Almighty), a dedication made to the Great Holy Congregation (Remarks: no. 1), 'May we would gain to see the redemption ofZion' (Based on the Benediction over the meal), by the dear Rabbi Yom Tov Atias, May the Lord sustain and protect him."
A Star of David is engraved on the back of the plaque

The custom of donating silver plaques as sacred objects is unique to these communities. Some inscriptions do reveal that occasionally they were donated with other ritual objects, such as a Torah scroll, a parokhet, or a mappah.
