Can anyone explain when the milled edge of the £1 coin is added. Is it before, after or at the same time as the front and back is struck?
The reason for asking is that I've been saving these coins when I got any in my change since they were first introduced in 2016. I had saved £1,100 before paying them in. Taking the top of the thistle as a reference point, following the top of it over to the edge, it is in line with a milled part. However, out of 1100 coins on 30 of them the thistle is in line with a smooth edge.
Now if the edge was produced before or after the front and back was struck then I would have thought that there would be a 50/50 chance of the thistle being in line with a smooth or milled edge. Likewise if it was produced at the same time then every coin would be the same.
So the question is why were only 30 out of 1100 coins show the thistle in line with a smooth part of the edge.
