Some people ask "Why should I invest in in rare gold coins?" Then answer quite simply is in the question. The vehicle you are investing is in two things. Its rare. And its gold. Gold has the protection of never going to zero in any currency while the rareness of the coin gives you the investment aspect of leverage. To put it another way, many people invest in gold stocks for the leverage against the gold price. The problem with gold stocks, like any stock, a company can dilute itself down, hedge itself down or spiral its costs so high that the stock goes down. So you are taking a chance when you buy stocks. The same is not true with rare gold coins. They are finite in number and they are gold providing leverage and protection.
