Nigeria, we need to separate some different types? [opgelost]

Hi everyone,
Regarding the Nigerian coin catalog, I consider that there are a series of types / pages that should be separate and not together as they are at the moment.

Following the criteria of other countries, where some difference in the emblem is sufficient reason to consider two different types / pages, such as:
Madagascar (two mottos = two different types / pages):

Oman (two emblems = two different types / pages)

https://en.numista.com/catalogue/pieces188742.html

In the case of Nigeria, I think the types / pages that should be differentiated are as follows:

1 KOBO:

This page I think should be separated into two different ones:
KM 8.1 Motto 1 (UNITY AND FAITH) Years 1973-1974
KM 8.2 Motto 2 (UNITY AND FAITH, PEACE AND PROGRESS) Years 1987-1988

5 KOBO:

This page I think should be separated into two different ones:
KM 9.1 Motto 1 (UNITY AND FAITH) Years 1973-1986
KM 9.2 Motto 2 (UNITY AND FAITH, PEACE AND PROGRESS) Years 1987-1989

10 KOBO:

This page I think should be separated into two different ones:
KM 10.1 Motto 1 (UNITY AND FAITH) Years 1973-1976
KM 10.2 Motto 2 (UNITY AND FAITH, PEACE AND PROGRESS) Years 1987-1990

50 KOBO:

I think this page should be separated into two different ones, since the change of shape is usually reason enough to differentiate into two types / pages:
KM 13.1 Shape: 12 sided (dodecagonal) Year 1991
KM 13.2 Shape: round. Year 1993

I wait for your opinion, regards, Oscar

I'm in complete agreement regarding the 1, 5 and 10 kobo. For the 50 kobo, it's a little less clear cut, as the 1993 is not actually round, just less "sharp" in its corners. This website has images

Sadly, I only have the 1991 type, so I can't make a direct comparison myself.

Hello. It's done.

Hi, many thanks for it,Cyrillius.
