Doubled die from Italy???

[andrea78ts]

Hello everyone! This is my first post on this board. My name is Andrea and I’m from Italy.
I would need your help to identify which kind of error it is.
This a famous and rare Italian (error) coin 2 cent 1915 called “quattro mani”, translated in English: “four hands” or it should be better: “four arms”. In all main Italian coin catalogues it is reported as a double strike error, but in my opinion it isn’t, mainly because there are more than one identical coins with the same doubled design.
I think it could be a “doubled die error”, but I can’t understand the reason why just some details of the design (particularly the arms and ribbons of the dress) are doubled…please compare the standard coin with the error coins.
Can someone help me to solve this mystery which lasts almost 100 years in Italy?
Thanks
Andrea

It is a very dramatic doubled die, indeed. It appears to be a Class IV doubled die (offset hub doubling) restricted to the center of the design. This would indicate that the first impression the hub made on the cone-shaped face of the blank working die did not progress very far. Only the apex of the cone received an impression. On the next attempt, the hub (or die) was repositioned and the full impression of the hub was received by the die in a position offset from the first.

Thanks! It sounds very reasonable and clever as explanation.
Furthermore, it is interesting to know that there is another version (less known) of "central" doubled die error of the same coin ("three arms").
1915 was not a lucky year for this coin or it depends from the point of view, in my opinion it is a fantastic year!
