This vintage silver small pin weighs 3 g and measures 23.5 mm x 20 mm. This is an older piece, that has had a replacement clasp. The current clasp does work very well on the pin. The marks on the back indicate several things. The harp indicates it is sterling silver from Dublin. The woman sitting indicates this piece is from Dublin, Ireland and the O stands for when the piece was tested for content. After researching it seems this pin dates back to the year 1863. The enamel is in good condition and the piece has not been cleaned. It would be appropriate for either a man on his lapel or a lady. Please take a moment to view our other pieces for sale.
