Vintage Silver Filigree MANDOLIN BROOCH

Beautiful and ornate vintage silver filigree mandolin brooch. there is a marking on the back but it is eligible due to age and wear. a few years ago i had it professionally cleaned and the jeweler stated it was indeed silver and likely 1950s. i do not have any appraisel or certification so its priced low. there is significant wear and some surface scratches consistent with a piece of this vintage. the brooch pin and clasp are original and work well. from a smoke and pet free home offers are welcome
