Arc Angel Value

[methadoneman]

I've had this knife since 2010 and it wasn't new then. It's never been sharpened and although one of the pics looks like it has a rust spot it doesn't and only has dirt and grime and a few spots on it where its carbon steel. I could easily remove those with an eraser but I don't want to do anything to effect the value of my knife. It got wiped with a sentry tuff cloth in 2010 and put in my case. It hadn't been touched until the last few days when I pulled it out trying to find the value for a possible sale. If anyone can give me an approximate value I would be grateful because online I see prices all over the place. Sorry for the bad pics, I can take more if anyone tells me that they want me to.
