old glove

I was given an old glove when I was around 10(1967)by an old neighbor in his 70's. The name on the glove appears to be Jay Keesey. It is a Nokona model, J308. It also has "The Latch" written on the inside of the glove. Any idea what year the glove came out and how much it would be worth on the market? thanks for any responses.
