1) There are, most certainly, type II 1981 proofs for all 6
nickel type II is actually cheaper than the type I, but the dime quarter
and half all carry premiums of their own for type IIs. The cent & dollar
are by far the highest priced and perhaps this is why you don't see a
listing for the other denominations, although the half retails around
$8-$9 so I am surprised to hear you say its not listed. If anyone is
interested, I'll post a listing of the various single coin bids from the
greysheet, where they carry roll bid prices for all 6 coins.
2) It is incorrect to refer to the '81 mintmarks as "filled" or "clear"
in determining value. These characteristics are determined by the force
with which the mintmark was punched into the die and the terms are totally
irrelevant as to whether the mintmark is a I or a II. The distinguishing
features of the 81 type II mintmark are in the >shape< of the upper &
lower loops. The type I 1981 actually has a perfectly round upper loop
(after all, its really the 1979 type II punch!!) while the 81 type II has
a slightly horizontally flattened appearance. In retrospect, it would
have been much less confusinng had we named them type I, II, and III
because the 79 type II and the
81 type I are exactly the same. They are the same punch.
