My collection's catalogued using Excel. I have a colour coding to indicate the more expensive items.
My partner knows this but I suspect when the time comes she'll look to offload it as one collection. It's going to be an inconvenience for her so I'm more than happy for her to do with it whatsoever she chooses. I have friends that will advise her if she wishes and a trusted shop that she knows about. I'm more than happy for it all to be donated to Oxfam - that's where I purchased the most expensive item in the collection from. I have had fun from it all, let others enjoy and look after them.
In the last years I sold on discogs or record stores most of the stuff I didn’t listen to anymore, mainly cds and less valuable LPs, rock and other genres. Now I am thinking to sell on discogs the most valuable stuff I don’t listen to anymore. All the stuff I bought in my compulsive eras, like audiophile records that are very sought nowadays. Mosaic and jazz stuff, including a fair amount of now crazy expensive originals, will be at my disposal in my last years. I filed all on discogs for my heirs. Selling online may be an job but for valuable records is well paid.
