[G6Tanuki]

There's a counterbalancing theory that says reducing the number of a given thing in existence will raise the value of those that remain.

Supply vs Demand. I don't see much of a demand for old tellies/radiograms - as reflected in how many of them get offered FOC on various social-media/community forums but which have zero takeup.

"Antiques" are only valuable because there is a limited supply. If there were millions of Mona Lisas or Venus de Milos out there, they'd be essentially worthless.
