I am surprised that more people are not investing in coins and other items at the moment. There is a distrust of the banks and so people are looking for other places to keep their money. Buying items with it, such as the kennedy half dollar and then selling them when they increase in value, could be something they could do.
Obviously, investing in anything is a risk and coins could be just as much a risk as a bank. Their values can change as well. However, this does not stop many people trusting them as an investment and their return can be very good.
If you are looking for a different type of investment, then this could be something worth considering.
