“The Supreme Court’s decision means that the coins will remain the property of the federal government and will not be returned to the Langbord family, which reportedly discovered the 10 coins in a family safe deposit box in 2003. The family — Joan Langbord and her sons, Roy and David — turned them over to the United States Mint in 2004 for authentication. Mint officials informed the family in 2005 that it was keeping the coins. A legal battle over ownership ensued, with both parties to the suit at different points being awarded the coins.”
