Classic Tuner

I no longer no how long I have owned the Kenwood T 917 tuner. It is in excellent condition. I have just returned to my home and in reorganizing things, I wonder if this tuner, which I was told was a great buy at the time and approaching state of the art in FM listening. I wonder if that information is true. I wonder if I should just dump it or it has value and I can sell it. Any opinions or knowledge out there? Thanks.
