A member of the public made an intriguing discovery while diving off the coast of Sardinia, Italy. The individual found over 30,000 large bronze coins dating back to the fourth century AD. This find, according to the Italian culture ministry, suggests the possibility of a shipwreck. The diver initially noticed some "metal remains" in shallow water near Arzachena. Subsequently, it was determined that these were "follis" coins, which were Roman bronze or copper coins later utilized as Byzantine currency.
The follis were found in a sandy clearing that could also contain the wreck of the ship transporting them.
The ministry stated that the total number of coins in the find, estimated to be between 30,000 and 50,000, surpasses the 2013 discovery of the 22,888 follis hoard in Seaton, United Kingdom.
All the retrieved coins are exceptionally well-preserved, with only four showing slight damage but still readable. The statement reveals that these coins were minted between 324 and 340 CE, originating from various mints throughout the Roman empire.
"The discovery showcases the remarkable historical significance of our underwater archaeological heritage, which has safeguarded and preserved the treasures of human civilization and trade throughout ancient times," commented Luigi La Rocca, the region's Director General of Archaeology, Fine Arts, and Landscape.
All but four of the follis are said to be exceptionally well preserved.
The Italian Ministry of Culture suggested that the area where the coins were discovered, situated in a sandy clearing between the beach and a seagrass zone, could potentially safeguard a sunken ship. Additionally, remnants of African and eastern-made amphorae were unearthed, which are tall, slim-necked jugs with two handles, commonly associated with Roman or Greek origins.
La Rocca stated that the treasure uncovered in the waters of Arzachena is among the most significant numismatic discoveries in recent times. He emphasized the region's exceptional heritage but also emphasized its vulnerability to both natural events and human activities. CNN's Sharon Braithwaite contributed to this report.
