Uknown copper? coin. [opgelost]

Hello!

I need help identifying a coin.

The coin has a diameter of 23 mm.

Composition: Copper?
The weight is currently not available, but I’ve added a comparison photo alongside this coin: N#1405, which has a weight of 5.66 g and a diameter of 23.6 mm.

If you rotate the left photo 180 degrees you get what looks like a crowned coat of arms, though I don't recognize from where.

All we can say so far is that the coin has bits of Islamic script, the  Arabesque pattern is found on coins of North Africa such as Egypt, Turkey and elsewhere

My guess is this is a Timurid coin

Indeed the lattice can be found in the Alaouite coins, but they look different, I guess.

I do not see any coat of arms.

Thank you all for the helpful comments!

I’ll look into the Timurid suggestion, and I appreciate the notes about the Islamic script and Arabesque patterns.

After long time of searching I think I found it!
