NRS 205.0831

“Value” means the fair market value of the property or services at the time of the theft. The value of a written instrument which does not have a readily ascertainable market value is the greater of the face amount of the instrument less the portion satisfied or the amount of economic loss to the owner of the instrument resulting from the deprivation of the instrument. The trier of fact shall determine the value of all other property whose value is not readily ascertainable, and may, in making that determination, consider all relevant evidence, including evidence of the value of the property to its owner.
