Kid, I don't think I'd give $800 for it. I can't make out the serial # to date the gun but it looks like 1960's maybe. Although 9 mm. is not my favorite caliber I wouldn't pass it up because of that.The Commander is one of my favorites, especially early ones that are real Commanders[aluminium frame] but once the anodized finish is worn as badly as that one it is going to be a "knock around" shooter or, you can polish the frame [which makes a good looking piece], or you can try to find an industrial anodize plater. Either way,it's never going to be a collectible original again. As a shooter,I would try to stay between $500 and $600 but I'm always looking for bargains!Check the serial # and let us see what year it is from. Good luck, Nick
