Well gold is very rare to find in many places. Gold is also very difficult to counterfeit.Gold is fungible & exchangeable because every bit of .999 fine gold is similar enough to be like another. Gold does not rust as it's imperishable. These properties make gold a good store of value, a medium of exchange, and a unit of account. Therefore, gold is easily trad able with a narrow spread, meaning it has a small price between the bid and ask the prices to buy and sell. Gold is therefore the ultimate liquid asset, a luxury, and is why gold is money. Silver is harder than gold but softer than copper.
Gold
because it is more rare and silver is more heavy there for less portable | | Have to partially disagree with the above statement. Gold is more rare than silver while it is still in the ground. There is actually more processed gold in the world than silver. Silver is not heavier than gold. It is heavier in 'value' than gold and therefor not as portable. So why is gold more valuable than silver? Short answer - because people made it more valuable. Apparently, they like gold better. | | Gold also has more valuable industrial uses then silver for example: gold is more resistant to corrosion. Gold is also a good conductor of electricity, particularly because it resists corrosion i.e. silver actually conducts better then silver until it begins to corrode (charging metal tends to speed up corrosion). So it's not just that we 'like' gold more, there are practical reasons why gold is more valuable.
18KT is gold that has been alloyed with a high percentage of copper and silver. 18Kt gold with more copper blended with it looks more red, and 18KT blended with silver alone looks more green.
Silver the very best conductorCopper the industrial choiceIron
Brass, which is made from copper and lead.
It si much rarer and harder to extract
Copper is much more common than gold.

Both are silver plated, but silver on copper tells you what kind of metal is used as an underlay. Silver plated copper is more valuable than silver on a white metal or zinc underlay.
Copper ......
18KT is gold that has been alloyed with a high percentage of copper and silver. 18Kt gold with more copper blended with it looks more red, and 18KT blended with silver alone looks more green.
pure gold (24k) vs 41.7% (10k) gold.. you decide.
Gold was then, as it is now; valuable. You could buy more with a gold coin than you could with a copper coin.
