Welcome to MauserGuns, Don! Overall, this would not be a very good HSc to begin or add to a collection. The grey coating indicates it has been refinished and the Magazine looks like it might be 1970's vintage which is not the proper size for this pistol.
Without more specifics, i.e., full serial number, matching serial numbers, marking on left Trigger Guard, markings on inside of the Grip panels, I couldn't give you a good valuation. From the little information you have provided, I would say it's probably a "shooter" worth perhaps $250 to $350 with little or no collector value and you may have to purchase a proper Magazine to make it fully functional.
Anything else, let me know.
