Appraising

Appraising(Rogue, 1)
Ability: Intelligence
Modifier: 0
This proficiency is highly useful for thieves, as it allows characters to estimate the value and authenticity of antiques, artobjects, jewelry, cut gemstones, or other crafted items they find (although the DM can exclude those items too exotic or rare tobe well known). The character must have the item in hand to examine. This skill allows the character to make generally accurate (+ or –10%) assessments of common objects, including items made of precious metals and gemstones. The charactercan also assess, to + or –25%, the value of objects of art, tapestries, furniture, weapons, etc.—provided a variety of these items are present in the game world. These assessments require no proficiency checks, and the DM can roll (d20 or d100) todetermine the accuracy of the appraisal. A character who passes a proficiency check will be able to identify a forgery of a valuable object, to make a very accurate assessment of the value of a common item (within 5%), or to make a general assessment of the worth of an uncommon item,including artifacts.
