    I was given several boxes of never opened RC Paper however it was very old but I don't know the exact. Only one pack of 25ct had a date written on it which said 1995. I opened the pack and it appears to be bad. The lady I got them from said she couldn't remember when she bought them but they were kept dry in her basement. The fiber based paper worked wonderfully and I was hoping the other boxes were fiber as well but alas they weren't.

    Is there an expiration date?

    If you opened the pack of papers and exposed them to light, then they are all ruined.

    it will depend on the brand, and how they have been stored.
    A basement could mean anything.

    if the paper is fogged it will be some shade of gray. You could always make photograms for fun from the fogged paper.

    The date at which paper becomes perceptably fogged depends upon storage conditions -- primarily temperature.

    The classic test for fogging is to place half of a sheet in developer for 2 minutes and then process it and the other half piece through your normal stop bath, fixer, wash and dry procedure. Then compare the two.
