What we found out was pretty surprising: my sister had a lot of antique dolls in her collection. Even her old Barbie dolls were worth something. A lot of people assume that old Barbies aren't worth anything because so many girls buy them as kids. They assume that there will be tens of thousands of any model still floating around. What people don't realize is that most kids toys get broken, thrown away, or lost eventually. If you have old dolls in good condition, the chances are that they are worth something to someone. Maybe you won't make a fortune on them, but they're still worth holding onto and seeing if you can find a buyer.
