Archaeologists have recently discovered a remarkably unusual cache of 2000-year-old copper coins within the remains of a Buddhist shrine, constructed at the historic site of Mohenjo Daro (Pakistan).  Mohenjo Daro, or "Mound of the Dead" is an ancient Indus Valley Civilization city that flourished between 2600 and 1900 BCE. It lies in Pakistan's Sindh province, on the bank of the Indus River. It was discovered in 1922 by R. D. Banerji, an officer of the Archaeological Survey of India. It was the largest city of the Indus civilization, and it probably served as the capital of an extensive state.
