"Archaeologists have discovered a precious golden dagger dated to
about 3,000BC in a Thracian tomb in the centre of Bulgaria. … The
dagger, made of an alloy of gold and platinum, was found near the
village of Dubovo.
… The alloy used in the latest find suggests a far greater degree
of sophistication in metal-working that was previously known for that
period."
