Walking away from Comic-Con last year, one collector scored two action figures from Ghostbusters for $20 apiece that now "can be found for sale online for $150." Not bad.

Makes me wish I had saved some of my old dolls and toys — what about you? Are you a collector? And if so, have you ever profited from hanging onto childhood keepsakes or memorabilia?
