Group 11, by modern IUPAC numbering, [1] is a group of chemical elements in the periodic table, consisting of copper (Cu), silver (Ag), gold (Au), and roentgenium (Rg), although no chemical experiments have yet been carried out to confirm that roentgenium behaves like the heavier homologue to gold.

In more specialized fields of study and applications the number of elements counted as noble metals can be smaller or larger. It is sometimes used for the three metals copper, silver, and gold which have filled d-bands, while it is often used mainly for silver and gold when discussing surface-enhanced Raman spectroscopy involving metal ...
Gold, silver and bronze or copper were the principal coinage metals of the ancient world, the medieval period and into the late modern period when the diversity of coinage metals increased. Coins are often made from more than one metal, either using alloys, coatings ( cladding / plating ) or bimetallic configurations.
In 2012, the Perth Mint produced a 1-tonne coin of 99.99% pure gold with a face value of $1 million AUD, making it the largest minted coin in the world with a gold value of around $50 million AUD. [2] China has produced coins in very limited quantities (less than 20 pieces minted) that exceed 8 kilograms (260 ozt) of gold.
The GLD ETF represents fractional, undivided beneficial ownership interests in a trust whose sole assets are gold bullion on and, from time to time, cash. The truth is that precious metals don’t ...
It is in group 11, like the other coinage metals, and is expected to be chemically similar to gold. [17] On the other hand, being extremely radioactive and short-lived, it cannot actually be used for coinage as the name suggests, and on that basis it is sometimes excluded. [18] ^b triels (group 13), from Greek tri: three, III [13] [16]
The iShares Gold Trust (NYSEARCA:IAU) is another gold ETF you can't go wrong with. Shares go for around $50 per share and boast a very attractive 0.25% expense ratio (it's a sponsor fee).
