The ratio between the values of silver and gold is around 85 to1, but it was over 100 till some days ago.
It means that a measure (1gr, 1Kg, 1 oz,…) of gold has a value of 85 measures of silver.
In the past that values haves been very smaller.
During the Roman empire, the ratio was about 12 to 1.
The US was fixed by law in 15 to 1 at the end of the 18th, more or less as it was later adopted by the Latin Monetary Union.
During the XXth century, the silver/gold ratio rose and climbed down many times changing between a maximum of around 98 to 1 and a minimum of around 15 to 1.
During the XXIth century, the silver/gold ratio has been always over 32 to 1 reaching 120 to 1 in march 2020.
There is no agreement between the experts on what would be the right value of the silver
to gold ratio. I think it is a bit strange that that value was more or less stable during hundreds of years of human history (Ancient Egyptians had considered silver more precious than gold for a period because they had only one silver mine) and now (during XXth e XXIth) gold outclasses silver in such a manner.
Maybe because gold is money, and silver is not only money but also an industrial material?
What could happen if the industrial sector restarted out massively as silver is used largely, especially but not only, in electronics and electrics fields: batteries, electronics components,…?
