Hi. This is my first posting. My father has many valuable items which he would like to sell but does not ever get around to doing so. One item is a book that he owns. It is in mint condition. It is preserved in a leather bound book case. It is a book written in Italian and published in Venice, Italy in 1609. It's called (translated) "The Immortal Glories". It deals with regulations in the Catholic Church. Would anyone know how much a book like this is worth and how to go about selling it?
