To add...
I purchased a US Mint case (500 oz) of Silver coins. I purchased at $20 an ounce. Which sucked as the price fell right after I purchased and only recently (4 years later) did it go up in value enough for me to reasonably cash out. Except I will not. When silver breaches 30 an ounce I may consider. That will all hinge on the canary in the coal mine... gold.
