help ID: 2018 commemorative coin from qatar

i need some info on these 2018 qatari coins, had them for years and still know nothing about them

40mm Wide

3mm Thick

both weigh 24 grams

You should test what material it is. Also, it's only a commemorative set, not legal tender, so if it's not gold or gold-plated, it won't be worth very much, about $20-$30 at the most.

With an apparent density of 6.4 g/cc it's not gold. 

A bullion gets a similar dseign from qgold.qa

N#55520

The composition is written on the coin 18/24 gold or plated ?

Google extracts the wording
