A Belgian shrimp fisherman rides a carthorse to haul a net out in the sea to catch shrimps during low tide at the coastal town of Oostduinkerke, Belgium July 3, 2015.

Nearly half a million of these coins were originally minted in the midst of the Great Depression in the US. Only 13 are known today after the rest were melted down before they ever left the US Mint, sacrificed as part of a strategy to stabalise the American economy. In 2002 a Double Eagle sold at auction for $7.6 million. (Photo by Peter Macdiarmid/Getty Images)
