A large Arabic copper coin [solved]

Please can someone help to identify this copper or bronze coin? It is 35.5 mm in diameter and is 2.4 mm thick with a reeded edge. It appears to have been struck using using worn dies. Many thanks.
Regnal year 8
Non est totum quod splendet ut aurum
Rijkdom bestaat niet uit het hebben van veel bezittingen, maar in het hebben van weinig behoeften
Thank you,
I see the Regnal Year number eight. Any further identification would be appreciated.
On the reverse, "duriba fi ..." = "struck in ..." and I think the name of the mint/city starts with "Umm ..." (... ام). What follows is unclear.

Sudan 20 Qirsh AH 1310/8 (1893) Omdurman mint.
There were many variations of details. Something more or less similar to this https://en.numista.com/catalogue/pieces17838.html
It's actually debased silver (about 10 percent silver).
I collect coins and tokens which circulated in Africa from 18th century to 2000. I sell about 7000 illustrated world coins from http://www.avscoins.com.
Thank you very much for the identification.
Best Regards
