Facts about Gold
Basic facts
Gold is a chemical
element with the symbol Au; and an atomic number of 79.
The Latin name for
gold is aurum.
Among the metals,
gold is the most malleable and ductile.
In nature, gold can
be found in nuggets or grains in rocks, as well as in alluvial deposits
and veins.
Pure gold is
chemically unreactive compared to other metals. Gold does not oxidize in
air or water. (However, gold does dissolve in mercury.)
Nitric acid can be
used to confirm the presence of gold in items. (This is the origin of the
term "acid test.")
Gold is a good
conductor of heat and electricity.
Pure metallic gold
has no taste.
Gold has only one
stable isotope, 197Au, which occurs naturally.
Gold is the official
state mineral of both Alaska and California.
Facts about gold coins
Gold was used for
national currencies for centuries. Even after the advent of paper
currency, national treasuries backed the money they issued in gold. (This
was known as the gold standard.)
During World War I
the belligerent nations converted to a fractional gold standard (and then
promptly inflated their national currencies). After World War II the gold
standard was replaced wholesale by a system of convertible currency
exchange.
Switzerland remained a lone
holdout to the gold standard for years. The Swiss government backed 40% of
its money supply in gold until Switzerland joined the International
Monetary Fund in 1999.
Pure gold is too soft
for use in coins. When used for coinage, it was typically hardened by
alloying it with other metals: usually copper, silver, nickel, or other
base metals.
The gold content of
gold alloys is measured in carats (k). Pure gold is designated as 24k.
Gold is often held in
storage (as bullion coin or bullion) as a hedge against inflation or other
economic uncertainties.
The ISO currency code
of gold bullion is XAU.
Gold coins minted
from the1520s through the 1930s (and intended for general circulation)
usually conformed to a standard 22k alloy. (This is called crown gold.)
An alloy was used to make the gold sufficiently hard.
Investment bullion
coins are typically 24k; they are softer than the 22k coins---but they are
not intended for circulation. (However, there are exceptions: The South
African Krugerrand and the American Gold Eagle are examples of older
investment grade coins that are still minted at 22k.)
The special issue
Canadian Gold Maple Leaf coin has the highest purity of any gold coin. It
guaranteed to be 99.999% pure.
Other modern gold
coins with high levels of purity include:
- Australia's Gold
Kangaroo (minted from 1986) 99.99% pure
- The American
Buffalo gold bullion coin (minted by the U.S. Mint since 2006) at 99.99%
pure
Gold bullion bars vs. coins
Precious metals in
bulk form are called bullion. Bullion is traded on commodity
markets.
Bullion metal is
usually cast into ingots (bars), or minted into coins.
Bullion coins are
technically issued as legal tender; but their face value as currency is
far below that of their value as an investment commodity. As an
investment, bullion (whether in ingot or coin form) is valued by its mass
and purity rather than by its face value.
Both gold bullion
bars and coins are priced on the basis of their fine gold content;
commissions and premiums from brokers may vary according to availability.
What is a bullion bank?
This is an investment
bank that deals in bullion. These banks might be called "bullion banks,"
or, alternatively, "bullion dealers." These investment banks are members
of the London Bullion Market Association.
Bullion banks are
wholesale suppliers. They typically deal in large quantities (usually over
1000 ounces).
How can a smaller/individual investor invest in gold?
There are many
financial instruments that allow individuals to invest in gold. In
addition to bars and coins, gold investments can also be made through gold
certificates, futures, and options.
Is gold a better investment than stocks?
There is no precise
answer to this question. But here are a few facts to consider:
Over time, there is
no relationship between returns on gold and returns on shares purchased in
major stock markets.
Gold and stocks are
fundamentally different assets. Gold is typically regarded as a static
store of value. Stocks, on the other hand, are bought with the
expectation of a return on value.
Like all commodities,
the price of gold is driven by supply and demand. Hoarding and bulk
selling can bring about dramatic price swings.
The price of gold is
more affected by sentiments than is the case with other commodities. Gold
prices are “emotion prone”.
Bank failures, war,
and low interest rates all increase the demand for gold.
Since 2001, the price
of gold has more than tripled in value against the US dollar.
