First of all, if your set had a "filled" S, the mintmark would be missing
from the coin. The Red Book has been using incorrect terms for both
varieties for a number of years.
The so-called "filled" S is actually a worn punch. It is distinguished by
a rectangular base rising from the field, with a weak S outline on the
In the latter part of 1979 a new mintmark punch was introduced. which has

there are openings into both the upper and lower loops. This punch was
used for the remainder of 1979, all of 1980 and the first part of 1981.

In the latter part of 1981 another new punch was introduced. This punch
has an identical, symetrical lower loop, but the upper loop is elongated
and flattened at the top, so it is not a perfect circle. This became the
1981 Type II punch.

term is meaningless. Both have openings at field level into the upper and
lower loops. The sole difference is the elongation of the upper loop,
which also has a different serif at the tip. However, the serif shape is
often altered by die polishing, so the elongation is the only permanent
