Like anything condition, and demand set the price. I just saw a 99% with box at the gun shop for $249.99. A quick stop to gunsamerica.com confirmed the price as fair.
$300
Value will depend on exact configuration, overall condition, finish, box, manual, accessories, serial number, barrel length, etc.. Range could be from 25 USD to multiple thousands of USD.
