10. This Archeological Gold is 6000 Years Old
Many significant archeological finds tend to come up when construction crews are working on the foundations of buildings. This gold turned up in Bulgaria in 1972 when crews were working in a factory near the Black Sea. It dates from about 4600 BCE, during the Copper Age. Archeologists came to the site and decided to keep digging to see if they could find more. They uncovered hundreds of graves, alongside a full 13 pounds of gold that had been worked into the designs shown in this photograph.
