Developing a hobby of collecting gold coins can prove to be a very expensive one. US gold coins are fascinating, so you find that many people who come across them and can afford to collect, start doing so if they are interested. Gold makes the world go round, remember the gold rush? That changed the destiny of many families. Have you seen how people react to gold? Even those who pretend to not even be remotely interested? From gold nuggets, to gold bars, golden biscuits and coins. Gold was actually used to make coins that were in mass circulation until it was phased out and metals and materials such as copper, nickel, silver and paper. When any trading was done with gold, it was the intrinsic value that was taken into account. With paper money however, it's the promise of the value to be paid by the government which takes precedence.
