If you buy rare coins through a dealer there is a possibility that you might never get your money back because you have to figure in the dealer profit. I have coins that were purchased from dealers in the 1970s that are still under water. If by chance you buy rare coins at wholesale (or preferably below) .... that might be a different story.
Tread slowly, sell some silver and buy some nice coins. See how you feel about it, and adjust your selling and buying accordingly.

Coming from a coin dealer, buy precious metals. They are the better investment currently. In the future, when metal prices rise, you can sell to buy rare coins. For now however, take advantages of the low prices of gold, and especially silver, because it will likely be a while before we see prices like these again.
