Silver Coins detected with Ground Scanner Rover C II in the Sechura Desert (Peru)
We are glad to present our customer’s find of a numismatic treasure – a witness to early currency reforms and noticeable effects on present world currencies: Several silver coins identified as Spanish Dollars were detected with the ground scanner OKM Rover C II in northern Peru and can be dated back to the late 16th century.
Pieces of Eight: The Basic Concept of World Currencies
The numismatic value of this find is fascinating in many respects: The coins became a popular trade currency of the Spanish Empire and still have impact on the designation of the present dollar. The discovery and conquest of mineral wealth in Peru and Mexico in the 15th and 16th century empowered the Spanish Empire and initiated early monetary reforms. One of the most famous silver coins of that time is the ‘Piece of Eight’, named after its divisibility into several bits. This concept is still common for breaking down currency values such as the US-Dollar into Half Dollar and Quarter Dollar.
