Can you still make quick money by selling off your family heirlooms? Many of us are tempted to raise cash by unloading the valuable stuff that's collecting dust in our basements. I recently went to the newly launched L.A. Flea Market at Dodger Stadium, and I brought you my first impressions of it last week. (Click here to see that video report.) In today's video, I dig a little deeper, and I talk to some of the vendors to find out what's selling now, and what isn't. Is it a good time to clean out your attic, or a better time to fill it? David Baiz, a certified appraiser, gave me the answer.
