When I started collecting Sasanians I was very young, it was about 1970. In those days there was one book about Sasanian coinage, very thorough, by Robert Göbl. I'm still using it after more than 50 years. In those days coins were cheap, but being a schoolboy, I didn't have much money anyway. But you didn't see Sasanian copper coins at all. Now this is different, and I have a few dozens of copper and lead Sasanians. This is my most recent coin, a tiny and thin little thing of only 0.63g and 13 mm. Like often happens, it is not exactly round, it's lightly worn, but still clear enough. Not easy to identify, but I think it's King Peroz (457-484) who minted it in his third period. His winged crown is jutting out of the pearl circle. Though the inscriptions are very small, the obverse one at the right of the head is more or less readable, it says 'Peroz' alright. It was offered as an Arabic coin and the reverse was depicted on its side. Well, then the picture looks like lines of Arabic text! But collectors of Sasanians immediately recognize the ubiquitous fire altar on steps and the two attendants. There may be text at the sides, but I can't read it. Can you?
Wow, what a wonderful little find. I think it's the first time I have seen one this small posted on here, but I could be wrong.
