#4: Stamp Collections

Stamp collecting, once a beloved pastime passed down through generations, has lost much of its shine and value. That old album tucked in your closet? Likely more sentimental than profitable. Many collectors don’t realize how pristine a stamp must be to fetch real money.

Unless it’s rare, flawless, and often over 70 years old, chances are it won’t wow the market. Most modern stamps are mass-produced and barely move the needle in value. Still, for some, the joy lies in the history and the hunt—not the price tag.
