Is buying the gold and silver dollars and commemoratives (Ha! As if I could afford Gold) from the U.S. mint a good investment? What about buying these coins from another company as graded and certified coins? Do these slabbed coins add value that will grow? And finally what about the ones that have been graded and signed by a former director of the mint? Does that add enough value to warrant a doubling of the price? Well, since I brought up gold, what about the smaller gold coins? Do they grow in value, too? I keep going back and forth between buying the coins and buying 1 oz silver bars. So many questions, I know. But that's what's been buzzing around in my head.
