Gold-plated cello music charm vintage

Vintage gold-plated cello violin charm from the 1950s or 1960s. Has no hallmark but has the type of surface texture common with Monet charms. Has diamond cut markings on the fret. No signs of damage, peeling or loss of gilt. Has some slight signs of wear on the back, though that could be the texture it's supposed to have. About the size of a quarter. Great gift for a music lover or string instrument musician.
