LALLA RooKH

I was given this book by my mother who came across it in an antique book store. I am trying to find out what it is worth..how old it is.and so on. It Is Lalla Rookh, by Thomas Moore. It has gold edged pages, a sketch ont he first page covered with wax paper to keep the image safe, as well at an image on the title page. It has gold paint etching ont he spine as well as the front cover. It is bound in brown leather and the pages are almost like cardstock heavy and stiff. There is some wear and tear on the book but other then that it is in great condition.
