While this die clash is not unusual in itself, the fact that it is on a off centered strike makes it noteworthy enough to be included in this site.
The die clash is rather shallow and will eventually fade after a small number of strikes. This gives rise to the possibility that the ckash and the offcenter strike may have happened in the same series of events, with the die clash happeneing first.
Because the strike is off centered, the date is unknown. However, the first digit is a 2 so we are confident that it happened in the 2000 decade.
The last two pictures show the clash on both the obverse and reverse dies.
