Yvonne Jordan, panel member on WXXI's ''Connections'' and the ''College of Collectible Knowledge'', will come to your home and provide you with a comprehensive one-hour appraisal of your antiques, art, or collectibles for insurance or sale value. This will include a written and notarized appraisal for your records. Approximately 30 items may be appraised within the hour. If the high-bidder needs a longer session, it would be at Ms. Jordan's usual hourly rate of $100. The location of the appraisal may not be more than 30 minutes from Rochester. This certificate has no expiration date.
