The last coin in the series «Gold Brooches» features a bubble fibula. The most ancient fibulae of this type were found in deposits of the 17th century.
Such fibulae were intended for fastening one's shirt and for its decoration. The large fibulae were used to pin shawls together. The bubble fibulae were common throughout the territory of Latvia and it represented not just ordinary jewellery but also significant value of that time.
Wealthy Latvian female farmers were proud of their luxurious brooches, which were often handed down from generation to generation. Such fibulae have often been preserved by families up to the present day as relics of their ancestors.
