  Radivojevic et al. (2013) reported the discovery of a tin bronze foil from the Pločnik archaeological site securely dated to c. 4650 BC as well as 14 other artefacts from Serbia and Bulgaria dated to before 4000 BC, showing that early tin bronze was more common than previously thought and developed independently in Europe 1500 years before the first tin bronze alloys in the Near East. The production of complex tin bronzes lasted for about 500 years in the Balkans. The authors reported that evidence for the production of such complex bronzes disappears at the end of the 5th millennium, coinciding with the "collapse of large cultural complexes in north-eastern Bulgaria and Thrace in the late fifth millennium BC". Tin bronzes using cassiterite tin were reintroduced to the area some 1500 years later.
  
  The oldest golden artefacts in the world (4600 – 4200 BC) were found in the Necropolis of Varna. These artefacts are on display in the Varna Archaeological Museum
  
  The Dabene Treasure was unearthed from 2004 to 2007 near Karlovo, Plovdiv Province, central Bulgaria. The whole treasure consists of 20,000 gold jewellery items from 18 to 23 carats. The most important of them was a dagger made of gold and platinum with an unusual edge. The treasure was dated to the end of the 3rd millennium BC. Scientists suggest that the Karlovo valley used to be a major crafts centre that exported golden jewellery all over Europe. It is considered one of the largest prehistoric golden treasures in the world.
