Well to tell you the truth, I am having some doubts about the kroner purchase. The only drawback I can see is that its not a well known coin. That may affect the resale value later on. On the plus side, there were only 243,000 made. Plus, it has a little more than a quarter of an ounce of gold. Most coins in the quarter ounce area have either exactly a quarter ounce or a little less. The kroner has .2592 ounces. 0092 of an ounce doesn't sound like much but when dealing with gold, a little is a lot, right? Its a good looking coin. Here's a link:
