Can someone explain the difference between white gold, yellow gold platinum, thank you?

22 Carat Gold Coins versus 24 Carat Gold Coins Almost daily we get find ourselves telling people that Krugerrands contain exactly the same amount of gold as Canadian maples. They seem to think that because Krugerrands are twenty two carat gold compared with twenty four carat for maples, that the Krugerrands contain less gold. All "One Ounce" gold bullion coins contain the same amount of gold.

Any 22 carat gold coins contain 1/11 of an ounce of "base" metal, usually copper, but sometimes with the addition of a small amount of silver. 22 Carat Gold Coins versus 24 Carat Gold Coins Almost daily we get find ourselves telling people that Krugerrands contain exactly the same amount of gold as Canadian maples.

All "One Ounce" gold bullion coins contain the same amount of gold. Any 22 carat gold coins contain 1/11 of an ounce of "base" metal, usually copper, but sometimes with the addition of a small amount of silver. Why 22 Carat Over thousands of years gold coins have been made to many different standards of purity.

By the 19th century, most countries struck gold at either .9166 (22 carat) or .900 fine, depending on whether their coinage systems were influenced more by British (22 carat), or continental European standards (.900). The USA for example used to use the continental .900 fineness in its gold coins, whereas Canada used 22 carat. Twenty two carat has been found over millennia to provide a good alloy for gold coins.

It is almost impervious to chemical attack and tarnishing, yet hard enough to withstand decades of wear and tear. Nine hundred gold is very close to 22 carat, and shares its properties. By the way, it is a popular misconception that the more base metal the harder the alloy.

The fact is that alloying creates controllable properties, so that alloys can be softened by annealing and hardened by working or quenching. Why 24 Carat Why not? The original purpose of gold coins was to circulate as everyday money, therefore they needed to be durable.

Coins intended purely for storage as bullion coins do not have this requirement, therefore there is no reason against using pure gold. We should explain that in practice it is difficult to refine any substance to 100% purity, therefore 24 carat gold is a slight approximation. It is more accurate to refer to it as .9999 gold.

There is a possible advantage that fine gold does not need to be alloyed, therefore removing several production stages, and pure gold coins can therefore be produced more cheaply than alloyed ones. Add to this the fact that some people, given a choice may have preference for one type over another, then the introduction of variety is desirable. It may also be that Canada wished to appeal to a different sector of the market when it decided to issue its famous gold maple leaves in pure gold rather than 22 carat.

Which are Which? British Britannias, American Eagles, and South African Krugerrands are all made of 22 carat gold. Austrian Philharmonikers, Australian Nuggets, Canadian Maples, and Chinese Pandas are all made of 24 carat gold.

"Real" Coins In addition British Sovereigns are made of 22 carat gold, and although they predate the concept of a one ounce coin, are an excellent, but often overlooked alternative. Many other, older gold coins were made of .900 gold including French and Swiss, but this does not reduce their value to the investor. These older coins were originally intended for circulation, and they were made in sizes and weights which suited their original purposes many years ago.

Sovereigns were first issued in 1489, and have retained their current format since 1817. There are advantages and disadvantages in buying these "real" coins instead of modern bullion coins. Minimum .900 The minimum accepted standard for gold coins to be treated as VAT free investment gold in the EU is 900 parts per thousand, equivalent to 21.60 carats.

I don't enderstand your question, I admit. A true coin would unlikey be made of 24k (too soft and too easily damaged). The most poular coin, minted for investment purposes is the krugerrand.

By 1980 the Krugerrand accounted for 90% of the global gold coin market. Maybe you are missing this point: the kruger contains exactly one Troy ounce of pure gold (24k). As the coin is 22k it weighs more than an ounce the difference being copper.

Any coin intended for circulation will be 22k.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
