Hi Kumarik,
welcome to the forum. Looking at the state of this coin, it probably does just about merit a posting in the 'hammered' category, as you have done?.
It is probably a fake, they have been widely forged, often with wrong die pairings and edge legends. The quality can be quite good,and weights normal. The problem is so great in terms of numbers in circulation that the design and shape of the £1 coin has been revised, for release in early 2017.
