Best advice is to not give the complete serial number of your firearms in an open forum, pass on the last three digits fill them in with XXX.
After that pictures help but much depends on your local market, a reasonable sources are the Blue Book of Gun Values, contacting the manufacturer, talking to local gun shops, gunbroker.com or google/bing search. It takes some effort to know the value of a firearm and that is on you to do your homework. I'll tell you there worth $50 and the cost of shipping, it isn't the true value but since you asked, here's my quote.
Those who hammer their guns into plows will plow for those who do not." ~ Thomas Jefferson
