(This is an appraisal from a rural town. Please be aware.) This is a "Sweetheart Pincushion" from the World War I era, a small keepsake handmade by soldiers as a gift for loved ones (wives, lovers, mothers, etc.) during their time in the war or while recovering in hospitals. The "MOA" engraving likely stands for "Moments of Alwaysness." Motif: It features a design of doves (pigeons), symbolizing peace, love, and hope, and green stones (such as emeralds or peridots) surrounding them. This is likely not silver, but rather plated. Also, we cannot provide anything to certify its value. The dirt is more noticeable on the cushion. We believe it is close to a vintage item.
