More info, please: Single Action? (Cowboy style) Double Action?
like an older police type. Caliber, name, model, etc should be found on the right side of the barrel in Rugers. Post this.
Is the gun stainless or blue? How long is the barrel ? Measure from absolute front of the barrel to the absolute end right in front of the cylinder. Wood or plastic grips? Is there a box, papers, etc with it? Is the gun looking like new or like junk or in between?
I have seen Single Six revolvers going for $250 - $350 depending on condition and where they were sold.
New ones are over $400.
They are excellent revolvers, and many use them as hunting/woods/plinking revolvers.
Keep it, don't sell it.
