1575
Cerro Rico already open
In 1575 Potosí’s silver working is already underway. Eight-real pieces are becoming empire coin. Amsterdam’s public bank is not open yet.

Major silver working at Cerro Rico began in the 1540s. Ore moved to a colonial mint, then into the fleet and into Eurasian payments. This year does not open a new mine on these pages.
The eight-real piece is the coin face of that silver. Venice’s Banco della Piazza di Rialto opens in 1587, after private-bank failures. The Wisselbank is 1609.
