You can expect to buy the entire 1963 Proof Set on Ebay for about $10-$20 including shipment . I agree with Super Dave , not a good deal.
There are rules regarding selling coins before your 10th post and they must be listed in the correct forum. Just letting you know.
If the poster is advertising his own coin for sale, I'm not believing the image. If the poster is requesting our opinion of that coin being offered by someone else, I'm not believing the image. Not that I'm a pessimist, you know.
