Lets look at disposal another way. First is no money involved. Since reading the replies I have changed my mind about trashing everything to my way of thinking (now), throwing the lot in a bin for the garbage tip everyone loses so if someone is not in a position to sell it leaves three options.
Donate to a club.
Donate to a charity of your choice (We have a Salvation Army store near us and will pick up we donate clothes and books to them )
Donate to friends.
I haven't said donate to your children as some might not have that option I know one of my sons would like some of the trains he has two sons who love them when they visit, maybe that's where some might go. I find it this an interesting topic and appreciate the replies I thank you all for that. I have to go the missus is yelling at me to get off the computer !
