100% vise job. One other thing that I would point out is that holding your coins like this with metal tweezers could add scratches to your coins. Cotton inspection gloves would be a better alternative. In the case of this coin it doesn't really matter, but hopefully you will find something really interesting soon and I'd hate to see it inadvertantly damaged.
