I agree with Terry,,, it is a personal thing for sure... I have had a few signs restored ,, sold them as restored signs,, as far as value goes,, IMO a restored sign is worth approx. half of a mint original sign..
I find it is a tough hard sell when you want to sell them explaining how much was restored what it looked before although I did have pictures of before. I like it better when a sign " is what it is " no explanations, you get what you see.. to me if your going to restore a sign why not just make a new one..
