Blue Book on the Howa 1500 rifle is about $400. The scope is an "off-brand" and personally I would not give it much value at all. Maybe $50 used , if not buggered up. The Ithaca 10ga. autoloader, if in good shape, is Blue Book for about $600+/-.
Looks like the shotgun is worth about $200.00 more than the Howa.
