There are definitely certain categories of antiques that are still appreciating in value and are in high demand. Art and midcentury furniture are the two that come to mind. Storing fragile, purposeless things has a real cost when people are renting, have small space, and/or are moving to different cities for work. To quote the trend, the objects really need to "spark joy" to be worth keeping. For example, about 10 years ago, my mother gave me a stack of truly awful decorative plates with cats painted on them, and I stored them as an "investment" because eBay had them for $60/ea. I checked last year and now they were selling for $4/ea, so I just put them out front in a free box for someone with different taste to enjoy. I don't even know why I had stored them all of those years, like I was going to get into the business of selling decorative plates if they appreciated in value or something.
