The value of ANY firearm is based on the exact make, model, and condition. Unfortunately, you did not tell us the make, model, or condition- only the caliber. A value could be anywhere from $10 for a cheap Spanish copy, to over a thousand for an excellent Smith & Wesson. Sorry- but good questions produce good answers.
