Coca-Cola Shares
In 2008, Tony Marohn purchased some old Palmer Union oil stock certificates from a garage sale for $5. He hoped to become a multimillionaire. Palmer Union was a company that eventually became Coca-Cola, so Marohn anticipated his new shares would be applicable to the beverage company. While Marohn passed away two years later, his family insisted that his shares were worth $130 million. Sadly (but somewhat expectedly) the U.S. legal system did not agree, as a judge ruled that Coca-Cola did not have to honor these shares.
