In the news, a California couple recently struck it rich when they literally found buried treasure on their property. They found 1,427 gold coins, nearly all in uncirculated mint condition, dating from 1847 to 1894. All totaled, estimates are that they may by worth some $10,000,000! Sadly it looks like some 47% of that will be owed to state and federal tax collectors.
