Sometimes the deep scratches require you to kick it up a notch. I had a 1909-S VDB MS63BN in a messed up PCGS holder. I never tried it before, but used my rotary tool on a couple of the deep scratches. There's a soft cloth polishing attachment that I used. Just keep the attachment wet at all times. I had some dvd/cd disc repair stuff lying around and used that. It worked fine. I probably could have sold the coin/holder as is, but had trouble getting decent photos. When I was done you couldn't even tell it was polished, looked good as new.
