Where is the gold ?

[Externet]

That gold mined centuries ago since ancient times, the gold from spaniard conquerors, the gold from mines production in all continents.

Physically, where is it ?

Cannot believe that a substantial amount is in jewelry or museums.   The amount of gold produced in say 3000 years, has to be a huge amount.  Where is it now ?

[Strange]

I guess most of it is in safes.
