This is an amazing brooch from Peru in the 1970's. It is a coin with wired dangles of natural stones and crystals. The brooch is hand made from brass with a safety pin type closure. The front of the coin has only a picture of a llama and the back has a shield and reads Banco Central De Reserva 1975. It measures 3 inches long ans has a nice patina. Very Bohemian Chic!
