We try not to keep worthless things by which I mean souvenirs we have been given or bought ourselves that don't really mean anything to us, or things that we neither use, nor see any forseeable use for.
A couple of years ago, I went through my parents' photo albums and sent the photos of my paternal relations to my cousins on that side of the family, as they had expressed a wish for them. No-one will want the photos from my mother's side, so they have gone out.
Old letters etc. have been gone through on the same principle.
DH has load of tools he uses and that I cannot, so if he dies first I shall sell what is saleable and give the rest away. The same applies to the books that he has, which do not appeal to me.
My will contains intructions that my estate is to offer my academic books to the University of Copenhagen, either for the use of the relevant library or to be given or sold to students, apart from a first edition of a quite rare book that is left to the Royal Library.
In your place OP I would make sure that your daughter knows that some of her father's photographic equipment is valuable, so she can decide if she wants to sell it or just give it away.
I see no reason to dispose of things we might still want to use or just to have, and I find it distressing that so many women seem to feel they have the right to badger their husbands on this matter.
I admit that clearing my parents' home was a nightmare as they had kept ever single bank statement and tax return from 1975 onwards, so I make sure I do not make that mistake.
I have promised myself that when the day comes when I no longer want to decorate a Christmas tree every year that I will make sure that I dispose suitably of all our Christmas decorations. And that if we decide to sell this house and move to sheltered accomodation - not something that is relevant just now, but who knows? then there will be other things that will not go with us (or me).
Apart from that I am not concerned about the matter, but I have made sure my son knows where to find our wills, birth and marriage certificates and the deeds of the house, and that he can find a list of insurance policies, computer log-in codes and anything else he will need to wind up our affairs., plus of course, funeral instructions.
