Encarta 95 comes with its manual and jewel case which has label wear on the front and back. The disc has light cosmetic scratches.
Encarta 97 is in a sleeve and the disc is in pristine condition.
Encarta 99 come its box, manual and jewel case. The jewel case is missing a tab so it separates from the back. The box which has had its top cut off. The disc is in pristine condition.
I do not know if these work on modern Operating Systems or not.
