Hello,
Thanks for approving me. This is my first post...
I have found a 2014 Shield 50p in my change which shows a remarkable amount of doubling on the reverse. Whilst googling I came across this post on the forum which shows very similar doubling on a 2013 Shield 50p. The consensus on that thread was that it was doubling, although before anyone could shed further light on which kind of doubling it was, the thread weirdly descended into talk about 10p coins.
I have researched doubled dies, but I'm not sure what type of doubling this would be. It depends on whether the Royal The Mint uses a single or double squeeze press, but I can't find any information about this on their website. I know that the US Mints changed to single squeeze presses in the late 90s.
I'm thinking that my coin could either be a Class IV Offset Hub Doubling or a Class IX Shifted Hub Doubling?
I know this coin is likely not valuable, as other examples (2013 and 2014 Shields) have sold recently for around 3 to 4 times face. But I am interested in error coins (particularly those from the US, where errors are much more widely collected and sought-after!) and would love to know just what kind of error this is.
Any help would be greatly appreciated!
Many thanks
