The great expense of refining the metal made the small available quantity of pure aluminium more valuable than gold. [16]
Spanish colonial coin of Philip II, minted in Potosí (modern-day Bolivia), struck c. 1580 The discovery of the New World and with it silver from Mexico and Peru ended the bullion famine by 1550.
