Below you'll find answers to some of the most common reader questions about 50 Surprising Facts You Never Knew About Gold.

What Is the Value of Gold?

The value of gold fluctuates all the time. As of August 2020, gold was worth $2000 per ounce. Generally, the value of gold tends to move inversely to the value of the US dollar. For example, when the value of a dollar increases, the price of gold drops as it is relatively more expensive for those in other countries to purchase. The opposite is likewise true and the same general principles apply to many other types of commodities as well.

Should I Invest in Gold?

Owning gold can act as a short-term hedge against inflation because its price tends to rise as the cost of living increases. Historically, gold can help mitigate the volatility of global financial uncertainty – which can make it a good way to diversify your portfolio. However, it is also important to know that from a tax perspective investing in gold or gold funds is considered the same as a collectible. As such, capital gains may be taxed at 28%, which is much higher than a typical investment.  As with any investment consideration, be sure to complete your own research or reach out to a financial advisor if you’re not sure about investing in gold.
