This is what childhood dreams are made of, folks. A couple in Northern California was walking their dog on their rural property when they uncovered $10 million in rare gold coins buried under an old tree last year. The coins date from the mid-to-late 1800s and are in mint condition, with many never having been circulated. At face value, the 1,427 pieces adds up to $27,000, but experts say some of them are so rare they could demand $1 million apiece. They are set to go on sale soon via Amazon.com's Collectibles site.
