As the items you list I have not used for years
But then...each to his or her own.
But trust me, everyone will ALWAYS need to sign their names to things ( and don't tell me about facial recognition, nor fingerprints, or whatever ), books, especially first editions, and signed ones, will only go up in value, the same is true re coins, pens ( good ones, such as Mont Blanc and others ), also increase in value since they too are collectables.
Just because you don't avail yourself of certain things, doesn't mean that others don't still use/want them.
