But if you wish to own coins there are indeed a number of bullion gold coins in the world. Bullion gold coins are used as an alternative form of wealth storage to traditional currency.
The attraction of bullion gold coins is that they retain near full value regardless of either change of government or being transported outside their country of issue.
These are not 'numismatic' gold coins. Bullion coins are not rare, and their value is simply computed by multiplying their gold content by the price. Numismatic coins on the other hand are rare coins and are considered collectibles. Numismatic gold coin prices are more volatile than bullion coin prices, because their prices move both with the changes in value of bullion gold, and with the emotions of coin collectors.

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.
As you can see, several governments are now minting gold coins again.
Generally these gold coins are not available direct from the producing mint. Instead the mints have arrangements with distributing sales agents who deal with the public. The mints themselves take a premium over the gold content (known as seignorage), and the agents add a further intermediary margin.
There is nowhere in the world that any of these gold coins circulate as money.
Gresham's Law states that "Bad money drives good money out of circulation". It applies brutally on gold coins.
Many gold bugs struggle to understand why gold is not a popular and widely circulating medium of exchange. Gresham's law explains it.
Imagine you had a pocket full of fast depreciating dollars (or any other currency), and a gold coin. You are about to pay for something and both are accepted by the merchant. Which do you choose?
That's all there is to it! Bad money is losing value all the time, so people wisely spend it, and save the good money. Not being used does not mean that gold coins are somehow inferior to bank-notes: quite the opposite in fact. It means that their good wealth storage characteristics means they don't circulate.
The result is self-reinforcing. Where there are lots of fast depreciating bank-notes about few people ever handle a gold coin, so they stop even accepting them when they are offered. They soon neither recognise the gold coin offered nor understand its value.
Then what tends to happen is that the skill to deal in gold coins (without getting duped by fakes) concentrates on a few expert gold coin dealers, and that increases the cost of dealing. They benefit from the value of their specialised knowledge, and you pay for your lack of it.
Nowadays gold coin dealing is perfectly legal and there is open trading of gold coins - usually tax free. Yet even now you will pay a premium of 6-10% above the underlying gold price for trading small numbers of gold coins with a gold coin dealer.
Then, when it comes to sell, you will have to accept a substantial discount for your gold coins too. That might cost you another 2-6%
Meanwhile should an economic meltdown occur your gold coins would probably not be very useful. One possibility is that they would be subject to compulsory purchase (confiscation) by a government at a significant discount to their real value - as happened in USA in 1933. Then the owner has either (i) to surrender his gold coins for a loss, (ii) to store them secretly, unused and unusable, or (iii) to dispose of them - dangerously - through illegal channels to underground gold coin traders, who will pay only a deeply discounted price.
Perhaps more likely - and indeed this has been the case for most countries for most of history - exchange controls will be re-introduced. You cannot carry or ship gold out of a country which is under exchange controls.
This is why people who understand the issues choose to store only a small emergency reserve as bullion gold coins. They expect to use them only in extreme circumstances. They put the bulk of their gold denominated wealth store offshore, and usually as close to a professional and highly liquid bullion market as they can. You too can do this using BullionVault.
If you can own gold in a country whose currency is not in crisis, which has a solid tradition of protecting foreigners' property rights, whose politics are stable, and whose enemies are few, then your gold will in almost all circumstances offer you better protection there than if you store it domestically.
That is why your gold coin purchase should be treated as your emergency reserve, and not as your strategic store of wealth.
