Ugandan shilling 50 cent and 1 shilling coin [Risolto]

According to Wikipedia (https://en.wikipedia.org/wiki/Ugandan_shilling), the 50 cent and 1 shilling coin was also minted in 1986. Numista referees, can you source that?

After a while of searching, I think I found them...

This link will give the best explaination:

Wiki says the last coins from the First shilling were issued in 1986; however, if the unissued coins from the above link are the same as the ones in question, the coins could have been struck in 1986, yet dated 1987 (since they were supposed to be released in 1987).

And the compositions of the 1 Shilling and 50 Cent pieces do match--they were nickel-plated steel.

So... maybe those ones?

(And I did send some requests to add these missing coins. )

​I found only the 1987 5 cent pieces.

In that link, the only pictures are of the 5 Cent piece. But it mentions the 1 Shilling existing, as well as the 10 and 20 Cents existing in Trial strike versions. There is a lack of information on the 50 Cent piece. But regardless, these types should only be found at the mint's museum (and I say should because... well, look at the 5 Cent piece).

The pages were approved. Here are the five of them:
