They look yummy, and if the quality is anything like the £20, well worth considering.
I have a standing order for the Collector Proof Set and the Annual Coin Set, supposed to be dispatched 3 December. I have all the 'round pound' mint and proof sets from 1983 to date, and all have been good quality. One time I received a proof set with a duplicate of the regular £2 coin and no commemorative.
I am looking forward to trying to find the 2014 2 pound coin with Lord Kitchener on it in change.
