Hi. There does seem to be a fractionally larger gap on the 1922  coin as showed by the photo above comparing it with the 1921 coin. It does not seem to be beads either more teeth when comparing on the 2nd photo i've posted. Its also bled. If you have a very zoomed up close look at the central trident it aits just below the teeth. Very hard to see but i appreciate my camera is not that good. Anyone else able to give me any ideas?
