Description: You can accurately discern (he date of an art object and sell it to a proper establishment for a higher-than-normal rate.

Prerequisites: INT 13, Arcane Spellcasting, Appraise (4 ranks)

You gain a +1 bonus on Appraise checks. By succeeding at a DC 20 Appraise check, you can discern the approximate age of a nonmagical art object (any treasure that isn't coins, gems, or jewelry). If you succeed at this check, you may sell the item to a college, museum, school, or university for more than its actual value, depending on the age of the item. You may only attempt the special Appraise check once. You must sell the item to an academic institution, and not to an individual, merchant, or shop. The age of the item determines how much more you can get for it, as shown on the following chart. Your DM might adjust the listed years to better match the age of his campaign world.
