Not much. Usually about $50-$150 depending on condition. They are a cheaper version of Iver Johnson revolvers. The first course of action to discern the value of a gun is to identify the make, model, manufacturing date, and variation. The book "Iver-Johnson Arms & Cycle Works Firearms 1871-1993" by W. Goforth will probably accomplish this. Then it's a simple matter of looking your gun up in one of the many firearm value books, such as the Blue Book of Gun Values, or the Standard Catalog of Firearms.

What model?
Need a DETAILED DESCRIPTION OF ALL MARKINGS, barrel length, grips, sights, box, accessories, papers, finish, etc..
What is the grip made of?
your revolver sounds like a 'break-open' type gun. probably from the 1930's or so. No value unless it's marked Colt or S&W. depending on condition i.e., gun is complete and functional. no pitts or rust. then anywhere from $75 to $150...........those type of 'break-opens' are a dime a dozen, and not too safe to shoot modern ammo.....
First of all describe the gun. Is it a revolver, or a shotgun? A revolver has a grip but so does a shotgun (actually a for end).
