Zaire 1, 5, 10 Zaire coins: is there possibly another 1 zaire type?

In my collection I have the 1987 1 and 5 zaire(s), as well as the 1988 10 zaires. They all have the same colour, like the yellowish colour shown for the 5 and 10 zaires coins on Numista: N#4432

N#6079

However, the 1 zaire on Numista has a copper color, not a brass color: N#9248

 Could there be two 1 Zaire types, a copper and a brass one? In that case another listing should be added for copper, in which the present copper looking coin picture can be shown. I can provide pictures for the brass coin.

When you have one or more 1987 1 Zaire coins, could you check the colour(s) please?

My 1, 5 and 10 zaire(s) coins:

The current photo just has bad lighting. You could add a better photo of your coin using the “Modify or add data on this page” link

Thanks for the quick info! I'll do that later with day light.

Brass excists in a wide variety of colors ranging from shiny-goldish-yellow to dark-brown.
I will check my Zaïre coins, later.
