That's a fair price if it has no scope. If it has scope the price would range from good to great, depending on the brand/model of optics.
Local shop had a nice used one in their consignment rack last summer. IIRC... it had an inexpensive Simmons scope, and an asking price of $595. It took a few weeks, but it finally sold. Knowing the shop well, I'd guess selling price was right at $500.
Good Luck....
