380/900 from 1990's? I don't know much but I would say not much. I have an autographed photo of Paul and it's probably worth around $400 and I saw him sign it!! I was standing shoulder to shoulder while he signed. Since Paul is still very much alive and kicking it probably won't be worth much until after he kicks the bucket. But then, as I said, I don't know much about it.
I would say possibly $100 but I am not an expert. When you find out, let us know. Much Luck.
