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.How much do you think these pictures from the original Disney movie are worth?
Well I looked for some and it seems they are called Production cels, and from the pages I found with prices it seemed to vary anywhere from $50 to over $500, plus the background ones seem to be worth more as I saw one for $5000



This one is listed for $800

These all seem to be listed at $500 - $900

So based on what I have seen, they may be worth at least $500 each. Good luck with selling them or whatever you plan to do with them.How much do you think these pictures from the original Disney movie are worth?
The best way to find out is to take them to disneyland or a disney corporation yourself and find out.
