Major surface rotation at hundred degree anticlockwise on reverse side position showing on centre scan of actual figures Please check it out on the scans below and let me knows of what you think later there
Unless you have the coin in a holder with an axis drawn on both sides, or you take a photo with the coin and a mirror behind it (and a little ways away), there is no way to tell if there is any rotation, because you can't see both sides at the same time.
You are right and agree with your statement its hard to make it clear unless grade in the holder or mirror to take picture of these
Is this a die axis error? I am not sure what you are pointing out. Nice coin with good toning by the way. John
