The value of your grandmother's mandolin would depend on its condition, demand for vintage mandolins, and any unique features it may have. Achille Lanfranco e Figlio was a well-known Italian mandolin maker in the late 19th century, so it could have some value to collectors or musicians interested in historical instruments. A professional appraisal or consultation with a vintage musical instrument expert would provide you with a more accurate estimation of its value.
