#10: Barbies

Barbie may embody glamour and glitz, but before you dig out your childhood collection expecting a windfall, temper those dreams. Unless you’ve got a pristine Grace Kelly “The Romance” Silkstone Barbie—one of the rare gems worth around $500—most dolls won’t fund your next shopping spree.

The reality? Loved, played-with Barbies typically fetch just a few dollars. While they may have strutted the Dreamhouse runway, their real value lies in nostalgia, not net worth. So, while Barbie’s world is fantastic, your collection’s payday might be more modest than magical.
