2010 COAT OF ARMS 50 CENT - ERROR ROTATED UPSET DIE PCGS AU58
The coin is showing die rotation error. It means the obverse and reverse dies were not aligned correctly when the coins were struck.
One can only speculate as to the reasons for the manufacture of this error. We would imagine that the coining dies are keyed to prevent them being installed out of alignment, so perhaps in this case the die was not keyed and it was installed incorrectly. Alternatively perhaps it was keyed but when the production die was hubbed perhaps it was out of alignment then.
