It's always a wrench having to chuck stuff out. Well, it is for me as I'm a bit of a hoarder. But lately I've had to take an "exterminate all the brutes" attitude to clearing out, so I've given a couple of boxes of gaming treasures to my wife to flog on Ebay. It's that or take them to the tip, and with classics like these that would be a crime.
There's sets of Imagine, Adventurer, Red Giant (with Brymstone by Robert Dale), and Fantasy Chronicles - including the issue above with Steve Foster's superb Christmas adventure which I still remember us playing in his house on Western Lane.
There are some scenario books, Chaosium games such as Big Rubble, gems like Bushido and Champions, and some figurines. Take a look if you have space for them. I'd like to think they'll go to a good home.
