What does AΘE mean?

[Minerva]

The characters are often found on coins, I have noticed them on the Athenian Owl Coins. "all Owls feature an AQE ethnic on the reverse, an ethnic being a type of legend identifying a people. The AQE ethnic is sometimes written in English instead as AOE or A-TH-E. The three Greek letters are alpha, theta, and epsilon, with the theta appearing as an O with a dot in the middle and having a TH sound. (In modern Greek theta is represented as an O with a line in the middle, while earlier in Greece it was represented as an O with either a cross or X in the middle). As with most ancient Greek coins, the genitive (possessive) case was used for the legend, so instead of "Athens" it means "Of the Athenians."
