and the word “centu” at the bottom and the “u” in that word comes in
two types; this is common to all denominations. On the second pass
thru the presses the value numeral was added and each of those has two
types.
As a result of combination, each denomination is found in at least
four types with a total of 37 types. The extra nine varieties arise from
the two digit numerals, which can have the two digits of either type.
Premiums for scarce types range up to 500%. All of this is well covered
by Michel, all type plate type positions are known and, as the stamps
aren’t too expensive to begin with, the interested fanatic could spend a
lot of type hunting them all down.
As you might expect, these are also found in se-tenants with different
types, so Michel lists 52 horizontal and 42 vertical such pairs!
Rounding things out are nine flavors of double and inverted overprints
and a dozen plate flaws (mostly broken letters), one of which is quite
valuable.

While the 5c on 300M was a necessary part of the above set, the
30c on 500M is difficult to explain. The only real difference between it
and its immediate predecessor was a change in the spelling of “centu” to
“cent.” for reasons unknown.
There are four plate types of the 5c and 5 of the 30c, plus the combination
se-tenants as with the preceding set. Taken together, the nine
items comprising these two sets had print quantities ranging from
100,000 to 220,000.
