I have had a few of these 2009 Family silver sets this one is #1295 of 1500 I am sure all the real coin collectors will find this a little boring and I only ask your advice because I have donated it to the charity and would like some idea of the rarity as a failure in the Royal mint not to have noticed 6 large pieces of silver on each of the edges. The metal twists down the side so much so that the coin will not ever sit in the capsule. It is sitting high and one slice of the silver is cutting into the plastic on the underside.
the weight for the silver proof is correct and all aspects of the coin are as they should be for the silver proofs except this. It must be very unusual to have struck it wrong, examined it , quality controlled it, then carefully placed it in the capsule where is doesn't even sit flush.
