1813 French Book Antique 17th Century Old

I got this book at an estate sale.  No idea what it says or what its worth.  I can't find the 1813 book anywhere on the internet.  However, I can find later published copies.  The 2010 reprinted copy is going for about $40+.  Not sure about a original 1st edition 200 year old book.  Condition is acceptable.  The front cover is missing, only hard cover on the back.  The front cover page is detached from book.  I would give it between 1-2-3-4 out of a 10 scale.  Please help if you have any clue what this is worth.  See attached photos. TITLE:  "Morceaux Choisis Des Lettres Edifiantes"  About religion/missions. YEAR:  1813
