John Dean1 reports two varieties of the 1928 sixpence. The normal
date has a fairly upright 8 and the scarcer variety has an 8 which tilts noticeably
to the left. Dion Skinner4 mentions a "small date figure 8"
variety which probably corresponds to Dean's left-tilting 8 and also a second variety
which has a dot in front of the 1 near the top. Robert Clarke2 lists
a "small high 8 in date" variety.
Whereas all three authors are probably in agreement, my own investigations suggest
that the situation is somewhat more complex. An examination of 23 specimens of the
coin showed that whereas the first three digits of the date are consistent with
those of the 1927 sixpence, at least three different numeral punches have been used
to make the 8. This observation strongly suggests that the 1928 sixpence represents
yet another instance where working dies were hobbed from a partial-date master puncheon
and the 8 was added by hand onto each individual working die.
Anyway, I have identified at least four varieties of the 1928 sixpence plus the
"dot-1" variety illustrated by Skinner.
8 has a small upper hole and a larger lower hole. The bottom of the 8 is very
This seems to be the most common variety.
