Like you I have a lot of jewelery that I no longer wear, and no-one to bequeath it to who will appreciate it. I also have a lot of silver cultlery I have inherited and various other "good" things.
My husband and I have dicussed selling some of the things that have no particular sentimental value, as we feel we might as well sell them for what we can get and use the money as a little extra, as we realise that we will not get a lot of money for these things.
Right now these plans have been shelved, as DH is seriously ill, so it seems tactless to talk about selling things right now, as we live in Denmark which has excellent health-care funded by our taxes, so we don't have to sell things.
Later, by which I mean, if I am left a widow far earlier than I had ever thought to be, then I will go ahead and sell and then decide what to do with the money that comes in.
There seems no point in hanging on to things that have no sentimental value when I know well that they will all end up in the nearest charity shop or the council dump after my death.
