?PBS’s “Antique’s Roadshow” begins its new season at 7 p.m. today on KCPT, Sunflower Broadband Channels 7 and 209. In honor of its debut, one of the show’s appraiser/prognosticators, Lark Mason, offers what trends to expect this year in collectibles:

• Large D-flawless diamonds and finer quality jewelry will be strong sellers, serving as a hedge for wealthy collectors in the turbulent economy.

• Post-war fine arts by top artists will be in great demand.

• Lower-end collectibles won’t be great sellers, especially outside of pop and mass culture items, so look for bargains here.

• Middle market (items under $10,000) decorative English, American and European furniture and decorative arts will continue to have a tough time, as this segment of the market competes against mass-market retailers offering reproductions of this material at affordable prices.
