I have a book of Luther's sermons from the late 1700s, in German. It was given to my dad when he was a young man, as a gift from a woman for whom he did occasional work around the house. Years later, he also found inside its pages a $1000 note from the Bank of the United States, issued during the Andrew Jackson presidency. We've never had either appraised and have wondered which is worth more. My guess is the book.
