Smart Talk finishes the week Friday with a show that will be a lot of fun.

Describe it as Antiques Roadshow on radio. David Cordier, President and CEO of Cordier Auctions and Appraisals, appears on Friday's show to discuss antiques, collecting, and value.

The program may be the most interactive one we've ever had. That's because we're encouraging you to either call the show at 800-729-7532 to describe an antique item that you have or send a description and photograph to [email protected]. Mr. Cordier will try to provide a rough estimate of its value, based on what he sees and hears.

Do you have a family heirloom that has been handed down or maybe something you've picked up along the way? Perhaps an old letter or postcard -- something with a famous person's signature on it?

Tune in to Friday's Smart Talk at 9 a.m. to hear more
