The Works and Correspondence of Edmund Burke - 1852

This set came from my grandparents estate a number of years ago. The complete title is "The Works and Correspondence of The Right Honourable Edmund Burke". It is an Eight volume set, printed in 1852 by Gilbert and Rivington Printers, St. John's Square, London. It's not in perfect condition, but it is complete, no tears, and the back cover of Volume One is detached but present. The inside covers and the edges of the paper are a beautiful, slick marbled print. I don't know much about the value of rare books, much less 18th century British nobility, but I am interested in finding out! It evidently mattered enough for my grandfather to keep it for decades, so it matters to me. Does anybody know any history of this item or its value?
