Thanks to Jack for the tip. I have plugged about half of my singles into discogs and can see the kind of values they are selling for. I've probably put all the good stuff in already and we're probably slipping into '80s novelties next, but you never know, they were not really in order. My most valuable so far seem to be
[] Feeder - Two Colours [] The Wannadies - You & Me Song [] Manson - Take It Easy Chicken [] Attic - All Plans Exist [*] Oasis - Don't Look Back In Anger
I don't even know who Attic are or how I came by that. Manson aka Mansun of course. There might still be some gems in there. I think Jack already pillaged most of the good stuff, or the stuff he thought was valuable.
Back in work today, started the beetle for the first time in about ten days and it fired up first time. That solar battery charger pays its way...
