This is a very high end proof set. Edit: I've received comments that the S on the eagle can't be seen. You can only see it under magnification or with a loupe. Please read the article I linked to above. Ok, I did my best to capture the S in a picture.
Contact me if you would like a picture of the S on the chest of the eagle. I assure you, it is a VERY nice coin.
