Well, my Photo skills are not the best Is it ok to link the actual Ebay-Auction? I am not the seller, but he cleaned the coin before shipping it to PCGS. Just for comparison reasons.
It would be okay to link it, but the color might limit the number and size of the bids. You also need to show the entire reverse.
I had a CC double eagle with a similar scratch once - came back from NGC with AU details due to the scratch. I didn't know enough at the time to try again - perhaps with PCGS. If I had that circumstance now I would definitely be willing to resubmit it - perhaps multiple times as in that case it would have made a huge difference in sale price. I had bought it raw and sold it for about what I paid for it as a details coing, but Live and learn. People have a lot of interesting resubmission stories here.
