I often heard news on gold coins or to other term called bullion in the stock market, how their value had remain stable for decades already. According to wikepedia :Gold has been used as money for many reasons. It is fungible, meaning that it can be traded easily, with a low spread between the prices to buy and sell. Gold is also easily transportable, as it has a high value to weight ratio, compared to other commodities, such as silver. Gold can be divided into smaller units, without destroying its value; it can also be melted into ingots, and re-coined. The density of gold is higher than most other metals, making it difficult to pass counterfeits. Gold is extremely nonreactive. The scarcity of gold stabilizes its value. Gold bullion is said to be the most liquid investment throughout the world.
On the movie, Dear John that I have watched and read the novel, The father of John was a coin collector, He had a lot of gold coins, keeping them all as their precious treasure. They hunt to buy bullion Even it meant sacrificing their meal just to own those rare coins to complete the collection ,they sometimes do it. Not realizing the value of that in the market if they are to sell their collection, I, imagine after watching that film and reading that book, how those gold coins would have improve their lives and how John would not need to apply in the military just to earn a living. It was just a thought and an option anyway. (smile)
