According to the information provided, the silver bracelet is engraved with "Fu Sheng Quan Yin", but it is not the mark of a certain brand or manufacturer's silver jewelry, so its specific value cannot be determined.

The value of silver bracelets will be affected by many factors, including purity, age, manufacturing technology, market demand and so on. Usually, silver bracelets are of higher value if they are antiques or have special historical significance.

If this silver bracelet is handed down from grandma, it may have special significance and value, because it is a family legacy handed down from generation to generation. But if we want to determine its specific value, we need to find a professional jewelry appraiser to evaluate it.
