Mozambique coins 1981

I can see that here in Numista, as in Krause catalogue, it appears the year 1981 in 4 coins:

- KM#98 - 50 Centavos
- KM#99 - 1 Metical
- KM#100 - 2.5 Meticais
- KM#101 - 5 Meticais

As I know, those dates don't exist in Mozambican coins. I was born here, collecting coins since 1975 and never saw those coins in circulation.
If somebody got the coins, show us the pictures.

I don't have any from 1981!

Ole

I also don't have them.
So gradually my Africa collection is getting complete, without adding more coins to it...

Interestingly year 1981 is listed in Schön-catalogue for KM# 98-101, too; but in separate line. Perhaps the author wasn't sure about existence of coins from 1981...

I also have no references for this date.
However, I am unable to delete the lines since there are 4 to 9 members claiming to have the coins.
As referee, I can only see the total number of owners of each date but not the names.
As far there is one owner the line cannot be deleted.
