Why in a world of barely a billion people was gold used to facilitate trade over other more precious metals like platinum? This must be due to the scarcity of plantium versus the population who's trade it was meant to facilitate?
Surely now in a world of over 6 billion people gold has reached the same ratio's as platinum used to hold. Surely now its time for silver to step up to the block.
The next backed currency will be silver - there must be no doubt?
Platinum has not been used as a trade metal in Europe because its existence has only been known to Europe for about 300 years, while gold has been known of for around 6,000 years (and probably longer).
In addition, how to work platinum has only been known to Europe for approx 140 years IIRC, thus reducing its stampability, its coinablility, and therefore its use as trade money.
So scarcity of platinum was not the reason it was not used, unless one accepts unknown-ness as the same as scarcity. By the time the use of platinum as a precious metal-backing currency was possible, precious metals as currency backing were on their way out, to be replaced by taxation as currency backing.
Contrary to what most precious-metals-as-currency-backers suggest, most currencies are still backed. They are backed by human labour and products, and - in some countries - a mix of human labour and commodities. The mechanism by which the backing is enforced is by taxation, which is used to pay the coupon - the interest - on national bonds (or gilts if issued by Britain). This taxation to pay bonds is what replaced precious metals as currency backing in the first half of the last century.
