There are a number of gold
bullion coins in circulation in the world. The attraction of these is that
they retain near full bullion value regardless of either change of
government or being transported outside their country of issue.

Gold coins were hardly
produced anywhere between 1933 and 1965. Then, once the private demand
for gold ownership had been nearly extinguished, it was finally the South
Africans who started minting again in earnest from 1967.
But there are still very
few gold coins around, and currently there is nowhere that they circulate
effectively as money.
There are practical
problems with gold being used directly as physical legal money. It is too
valuable to represent the smallest required unit of currency.
In America a dime
(ten cents) is equivalent to rather less than 1/100th of a gram
of gold. The physical size of a dime's worth of gold is a cube of edge 0.8
millimetres, i.e. about the size of a crystal of brown sugar.
This is far, far too
small to be practical. The smallest usable coin really needs a volume of at
least 150 times larger. This makes token coinage a necessity.
Token coinage systems
Any coin collection will clearly show
that by far the most common systems for coinage are indeed based on token
values. Governments decree that a given coin - worth in metallic terms
substantially less than its monetary face value - constitutes a legal
payment of a debt. To support this construct it has been necessary to forbid
independent manufacture of coins, and to assist enforcement by making the
technology of coin production relatively difficult to copy.
Deliberately overvalued coins tend to
stay in circulation precisely because they have no intrinsic metallic value,
which is a material advantage to the state, and even though in such systems
silver and gold coins are occasionally allowed to circulate in parallel and
in modest numbers their circulation generally declines (Gresham's
Law again).
Gold as a banking reserve
The unsuitability of using gold in coins
for cash transactions at the small end of the monetary scale is not the only
barrier to a gold centred currency. There are other difficulties in using a
gold based currency where large sums are involved.
For example, in modern economies normal
practice is that salaries are paid at the end of the month. There are more
than twenty million workers in the UK alone, and their earnings average
about $2,000 per month. So they are issued with approaching $40 billion at
each month end. This is equivalent to about 4,000 tonnes of gold and is a
figure achieved without taking into account any savings, or any of the
substantial monetary floats required to support non-salary related corporate
and government expenditure.
Yet the entire British central bank
reserve is only about 400 tonnes, which shows that Britain (like any other
western country) could not possibly underpin with gold the supply of its
national currency necessary to support the prevailing level of economic
activity, at least not without a massive increase in the pound sterling
value of gold.
The conundrum
So gold cannot easily work as a basis
for coinage unless its value falls substantially, while it cannot
fully back national money systems unless its value rises
substantially. Since one of the requirements of money is that it is
divisible, i.e. that it can simultaneously be used in small multiples to buy
small things, and big multiples to buy big things, it must be impossible for
gold to operate widely at both ends of the monetary scale simultaneously.
In fact where it has been used as money,
particularly in the larger economies of the modern world, it has tended to
be partnered with another material - usually silver - in a system known as
bimetallism. Invariably this suffered stresses because of the unavoidable
fluctuations in the respective values of the commodity content of the money.
So is gold money ?
The idea sacred to the maddest gold bugs
that gold should be the world’s only universal money is wrong, simply
because of the sums which prove that either at the small (coinage) end or at
the large (bank payments) end there has to be an alternative form of money
based on something else. History also shows them to be wrong - although not
everywhere and not all the time.
The historical records show that gold is
doomed only to repeat its temporary and peripheral role. But it is,
nonetheless, a vital role. When it comes back it makes its owners the
richest people around. We need a grasp of the history of
money to see how
this works.
