Wisselbank of Amsterdam established

The Bank of Amsterdam or Wisselbank was an early bank, vouched for by the city of Amsterdam, and established in 1609. It was the first public bank to offer accounts not directly convertible to coin. As such, it has been described by some as the first true central bank, even though that view is not uniformly shared. The Amsterdam Wisselbank was also active in the production of coins. For decades the assay master of the Bank sent out stocks of gold and silver to the various Mints in the United Netherlands to receive new coins in return.
