I am sorry to disappoint you, but I heard that antique bibles are fairly common as so many families have passed one down the line and consequently aren't worth much money. Of course the sentimental and historical value to your family are priceless.
And it's hoot, ''Mrs Beetons Cookery Book''.
It tells of not only 'how' to cook things, but how to manage household work, and help for people with 2 or less servants?
It really is a dear little book, but alas on opening it really is so old it makes me sneeze.
Not for a Saturday read for me :( to dusty!
