The Idaho Attorney General’s office has filed a lawsuit alleging that a former Coeur d’Alene coin store, its owner and its operator broke state consumer protection laws by failing to deliver gold and silver to customers who paid thousands of dollars in advance. The suit seeks $664,326 in restitution for 18 consumers who complained they were ripped off by CoiNuts Inc., its owner, Kevin E. Mitchell, of Hayden, and his stepdaughter and the store’s operator, Sarah M. Mitchell, of Hayden. The suit, filed Tuesday in Kootenai County District Court, also seeks $90,000 in civil penalties.
