If you are going to list it for sale, make sure to promote that the map is present and describe what it is.  A lot of buyers don't know that it should/could be there.  I don't know (or have forgotten) if there was a conclusive statement to say it was included with all copies or if the error was found after a number of copies had been distributed and sold.
