How much do you think these pictures from the original Disney movie are worth?

I have two pictures from a famous Disney movie and they are the original ones used in making the movie. They are in perfect shape and the movie is the Christmas Carol with all the Disney characters. They are the scenes when Donald is counting his money and when Micky and his family are stringing their key. These are not movie films. These are the actual pictures that are swiped to make the movie. I am just wondering how much they are worth.
