A number of major insurers have developed property and commercial general liability package programs for museums, historical societies, and other groups that have collections of art and antiquities. Coverage is also available for private and public collections of jewelry, antiques, and sports memorabilia, among others. Collections are written on an inland marine coverage form that usually covers flood, earthquake, theft, and damage due to changes in temperature and humidity. Insurers usually require that the insured initiate and maintain certain loss control efforts. This explanation of insurance benefits is provided by Insurance Marketplace.
