Gold Investment - Rust Free 

Gold, unlike some other forms of investment (cars, computers, etc.), doesn't rust away. In addition to this, despite being very soft naturally, gold can be alloyed with other metals to make it more durable for investment and other purposes. 

Gold bullion coins for example , especially those with a gold purity of less than 24 carat, are very durable. The reason for this is because gold alone is too soft to use in jewellery or to hold a form. It is therefore necessary to alloy gold with other metals such as copper, silver, nickel, zinc, etc. to make it harder and more durable.
