I’m not an expert, but, if you watch the PBS series Antiques Road Show you will see a lot of collectables have decreased in value since 2008 and some a considerable amount. They actually do “then vs now” comparison shows and often the “now” price is lower. The high end antique furniture market seems to have especially gone down. Is that a comparable? (See the recent thread about Dave Gilmour donating a lot of his guitars). I for one am selling anything I don’t use: “getting my affairs in order” as they used to say.
