l brought to friend to clean under microscope, because lemon juice and vinegar didt help at all! some black thing stuck like cement on coin..
I assumed it was Philip I because of the AVGG in the reverse inscription. But I just checked RIC, and there is an AEQVITAS AVGG from Antioch in the name of Philip II, so you are probably correct in your original attribution. I stand infected.
It's the reverse legend with AVGG that threw me off. Still, I'm not certain which Phillip it's from, but I will give in to the majority.
