Designer Labels
Vinyl Records
LPs are making a comeback, so perhaps you weren't planning to offload them anyway. But certain albums — from Britney Spears to Bob Dylan — are worth hundreds, even thousands.
First-Edition Books
While Marie Kondo says you shouldn't really have more than 30 books in your library, think twice before sending any first editions to Goodwill — especially if they're signed. When a famous author dies, those can be worth thousands.
Musical Instruments
We've all fancied ourselves giving a command performance or playing to a sold-out stadium, only to drop our lessons in favor of something less … difficult. Those instruments, however, stand the test of time. Used gear, in particular, retains its value.
Watches
Namely, luxury watches — and, specifically, a Rolex. It's "the only brand that is able to maintain the high resale value with the majority of its products," Ariel Adams, a watch expert, told Money magazine.
Comic Books
If you love comics, it's no secret that titles from the 1930s, '40s and '50s are worth an astonishing amount of money. While modern comics aren't quite as rare, they have potential value to collectors.
Antique Silverware
Perhaps you prefer a different look for your table, and that's fine. But don't let trends distract you from the inherent value of real silver silverware. Pay attention to brands like Tiffany, Gorham and Oneida.
