When I posted the Qatar 500 Riyal yesterday, I remembered this Yemeni 500 Riyal which I got when I was in Singapore recently. I was at a money changer when I saw this 500 Riyal in his glass cabinet and asked whether I could buy it. I can't remember what the cost was but it was relatively cheap and I managed to buy it. The colour and design really reminded me of that Qatari 500 Riyal. What do you think?
