Set of 5 leather books

This is a set of 5 antique Brown leather books.  They are dated from the early 1800s to the early 1900s.  They have some inscriptions of previous owners.  Some have plain Brown leather covers while some have marbled paper covers.  Although they look perfect from the spines, when on a shelf, one has a loose cover and there is some wear on the exterior edges of the covers.  One has a loose cover from cover.  That is not visible when it is on the shelf.
