cartoon cells–tom and jerry

I am looking for anyone who might help me with the worth of my cartoon cell circa hanna v. warners, I have tom and jerry the nurse, heckle and jeckle in zoots and the runnaway with the bandana and more given to me when I was 3 years old. I am 47, they are real and numbered. This is not a joke. the man was a friend of my dads, his daughter was laid off when the spit happened and took them out of the trash. He gave them to my dad for me because I reminded him of his daughter. I know the rumor is that they dont exist-i truley have some, I just need help finding out how much they are worth if anything at all
