Me too, I started collecting stamps when I was 12 or 13 and continued for several years. I have contacted three dealers to try to sell them and no one is interested in buying them.
I have my Dad'sold stamp collection.
Most interesting is a lot of German stamps from just before the war when he had a pen pal there
I think they met at a Scout Jamboree in Holland
pity he didn;t keep the letters - but the stamps are there anyway
I must admit to having some "problematic" stamps.
I have stamp collection started in the 60s which is probably worth 2p.
Expired passports going back to the early 70's. Not entirely useless as they serve as a sort of diary of the good old days when travel was fun.
Despite all my music now being streamed off Apple Music. I still have a Marrantz CD73 CD player in its original box from around 1985. It’s actually now worth quite a bit of money, but I can’t quite bring myself to part with it even though I no longer own a single CD!
