If the reported value of the property is two hundred fifty dollars ($250) or more and no owner appears and proves his or her ownership of the property within 90 days, the police department or sheriff’s department shall cause notice of the property to be published at least once in a newspaper of general circulation. If, after seven days following the first publication of the notice, no owner appears and proves his or her ownership of the property and the person who found or saved the property pays the cost of the publication, the title shall vest in the person who found or saved the property unless the property was found in the course of employment by an employee of any public agency, in which case the property shall be sold at public auction. Title to the property shall not vest in the person who found or saved the property or in the successful bidder at the public auction unless the cost of publication is first paid to the city, county, or city and county whose police or sheriff’s department caused the notice to be published.
