The Coggalbeg hoard is an Early Bronze Age hoard of goldwork jewellery dating to 4300–4000 BP. It was found in a bog at Coggalbeg, County Roscommon, Ireland in 1945, and consists of a gold lunula (a crescent shaped "little moon") and two small gold discs, of a type known from other examples, decorated with a cross motif within two circles. The pieces are flat and thin, and collectively weigh under 78 grams (2.8 oz), indicating that they were probably intended as part of a necklace.[2]
