. So the demand for these types of gold coins is not likely to fade away. There is no upper limit to which the prices of these gold coins can go up to as is evident from the 2002 auction. You may even purchase foreign varieties of rare gold coins. Countries with histories much more vast than USA's are literally a gold mine for these rare coins. The more limited a resource is, the more the demand will be for that resource in the coming future. An interesting fact is that rare gold coins produce significant profits even during periods when the price of gold is falling. For example, from 1988-1990, rare coins went up more than 665%, while the price of gold fell from $395 to $360 per ounce. So summing it up, you now have a way of diversifying your portfolio and venturing into a completely new form of ownership.
