is betamax worth anything?

[Dorota]

I have a bunch of the betamax Cartoon Classics Gold Edition tapes, Pluto, Donald, Silly Symphonies and bunch of others, 8 or 9 in all. All except one have the shrink wrap, though the wrap is slowly coming apart. Are these worth anything or anyone have any advice where I can sell these (except for ebay?)

any help is appreciated!
