Gold coins feature Snoopy

Gold coins featuring Snoopy

Investors disagree about whether precious metals make good investments, but anyone can buy American Gold Eagles, South African Krugerrands, or ancient Austrian coins at about the spot price of gold, which is hovering around $2,400 an ounce as of this writing.

But forget the big names and historic value. You can also visit Walmart's website to buy a real gold coin embossed with Snoopy — yes, the famous beagle. Or you purchase a gold coin that features Spider-Man or Han Solo.

You pay something of a premium for the image, but the coins are rated as authentic gold. Just be aware that investing in any gold is always about selling price. The old saying about this kind of investment: "There is only one thing rarer than a rare coin, and that's a rare coin buyer."
