It's not an error or variety coin, it just damaged.
It looks like the edge has been modified. The reeding has been smoothed out either by "spooning" or it could be a Dryer Coin. In either case, just PSD.
Sorry it's not something special, but keep looking and let us see what you find. You may find something that IS special!
