Long ignored sub-types for the early Nigerian decimal types

Newer pieces of KM-8, 9 and 10 actually have a longer motto.
Newer coins have a longer motto - KM-8, 9 & 10 listings require review.
(See end of this page to see whole of the coat of arms on each of these pieces.)

There is something about the Nigeria 1, 5 and 10 Kobo coins of types KM-8, 9 and 10 that seems to have gone unnoticed. It would seem that for all of these types a significant change was made for all pieces dated after 1976. The change is in the motto on the ribbon on the coat of arms on the obverse. Older pieces have the motto "UNITY AND FAITH" and newer (after 1976) pieces have the motto "UNITY AND FAITH   PEACE AND PROGRESS". To accommodate the longer motto these later pieces have a longer ribbon. I have a suitable selection of these coins though not yet one of each and every date - the longer ribbon pieces are harder to find especially the 1 Kobo. The longer motto is used on all of the 1990’s coins of Nigeria and it seems that perhaps the longer version of the motto is what should always have been used.

Taking this a little further - what do we have ?

We can now say....

1 Kobo coins come in a total of three varieties....
          a) 1973, 1974 - Bronze, short motto
          b) 1987, 1988 - Bronze, long motto
          c) 1991 - Copper-plated-Steel, reduced size, long motto

5 Kobo coins come in a total of two varieties....
          a) 1973, 1974, 1976 - short motto
          b) 1986, 1987, 1988, 1989 - long motto
          (I have also heard that there is definitely a 1984 date of this second sub-type.)

10 Kobo coins come in a total of three varieties....
          a) 1973, 1974, 1976 - Copper-Nickel, round, short motto
          b) 1987, 1988, 1989, 1990 - Copper-Nickel, round, long motto
          c) 1991 - Copper-plated-Steel, reduced size, rounded/multi-sided, long motto

25 Kobo coins come in a total of two varieties which differ in quite a number of ways.
          a) 1973, 1975 - Copper-Nickel, security edge, short motto
          b) 1991 - Copper-plated-Steel, reduced size, reeded edge, long motto

How could I have noticed this change if I had just been a "type collector" ?
 


Something you may have noticed on the 1991 and 1993 dated 50 Kobo coins (KM-13).

A few weeks ago someone brought it to my attention that the Nigerian 50 Kobo coins of 1991 are not quite the same as those of 1993. Currently the standard references read as though the coins of these two date are exactly the same type. However should you happen to have a pair of these coins you should be able to see for yourself that the 50 Kobo coins of these two dates are a different shape.

There are two differences to note...

Difference in 50 Kobo shapes - 1991 (above) and 1993 (below)
Difference in 50 Kobo (KM-13) shapes - 1991 (above) and 1993 (below).

The 1991 coins have 12 slightly rounded sides, the 1993 dated pieces are almost perfectly round
but only “almost”. An easy way to notice these differences is to roll the coins on a hard surface.

Edge reeding comparison - 1991 (above) and 1993 (below)
Difference in 50 Kobo (KM-13) edge reeding - 1991 stronger (above) and 1993 weaker (below).

Due to the flatness of the sides on the 1991 pieces the edge reeding is bolder
than on the 1993 pieces with their very rounded sides.

Maybe each date is from a different mint for KM-13 ? Who knows ?
I cannot see any differences in the 1991 and 1993 1 Naira coins (KM-14).

The information on the 50 Kobo varieties is as per the short item I had in the "From the Mailbox" section of the December 2001 edition of the Numismatics International Bulletin (page 338, pages numbered through the year). Some Lesotho coin info from me also appeared in that section of that edition (page 337). That edition was the first in which I had published Africa related information - since then I have had "Other Items", occasionally "Features" in more than ten other editions of the bulletin. It seems that perhaps not all of the 50 Kobo 1993 coins are so rounded.

The info above on 1, 5, 10, 25 Kobo sub-types was published in the February 2002 edition of the Numismatics International Bulletin (page 38). I had outlined these varieties to Krause publications some time before then - their SCWC now has an improved listing for these types.
