Debated. A Bronze Age ship sank with a very large cargo.
Off Uluburun, near Kaş in south-western Turkey, the wreck lay on a rocky slope about 44 to 52 metres down. The ship is about 3,300 years old and about 15 metres long, built of Lebanese cedar. More than 18,000 objects came from it. The main load was about 10 tons of copper, in 354 ingots, plus whole glass ingots coloured blue, turquoise, and pale purple. Jewels, beads, and small figurines were on board too. A gold seal names Queen Nefertiti. It is a scarab.
The page says the objects are not all identified yet, and it only believes the cargo was a royal order.
