The inner heptagon and the text (top) are not in the right place and are rotated 30 degrees or so CW. How would such a mint error occur?
I suppose this would count as a misaligned die, assuming it is an error? If so, I can't tell if the die was rotated enough to add value, but it is an interesting find.
I cannot find examples of this type of error on 20p coins with google.. in-fact this thread is one of the first results.. does anybody have a suggestion on how to find similar errors? is there a specific name for this kind of error?
This one would be interesting to see in person but I may have an answer. The inner heptagon is NOT misaligned. Notice the points of the inner heptagon line up fine with the outer legend right where they are supposed to. But the legend DOESN'T line up properly with the outer points of that heptagon. On this coin the planchets are multisided. Now imagine a normally struck coin. Now mentally keep the design in place but rotate the planchet. And there you have it the legend will line up with the inner polygon but be wrong with the outer one. Now since the coin is struck in a multisided collar you can't just rotate the planchet, so the collar has to be absent. There is your answer. This is a centered broadstrike with the multisided planchet rotated about 25 degrees.
