Palouche, Thank you for your opinion. Now I have another stupid question. Which side is considered the obverse and which is the reverse? Sorry to sound so dumb but as mentioned, I know absolutely nothing about ancients.
Not at all a dumb question, it is by no means self-evident what is the obverse and reverse of these coins. Usually for coins, it is the side with the emperor or king or other ruler that is considered the obverse. And here we have the emperor and Jesus ... For Byzantine coins with a portrait of Jesus (which is very common for Byzantine coins), it is always the side showing Jesus that is the obverse, considering Jesus to be the superior ruler. So for the coin here, on the linked page, the left picture is the obverse.
