I have an old book is it valuable or 1st edition? *Please Help!*?

Old books and values are a lot of fun. Boosey and Co and Hawkes and Son merged together in the 1930's to form Boosey and Hawkes so your book must be at least, previous to this, which is getting on for a hundred years old. But Boosey and Co were going at least another 100 years before that so it could be 200 years old! Religious books of that time do not usually command good prices as many were published but who knows, Raymond could be a famous person and his signature could send the price of an ordinary book sky high! It is probably a first edition but this doesn't by its self make it valuable. My advice is to keep it and find out all you can thorough the internet and book shops.
