Attic numerals

As in the basic Roman system, each part was written down using a combination of two symbols, representing one and five times that power of ten.

They are believed to have served as model for the Etruscan number system, although the two were nearly contemporary and the symbols are not obviously related.

Specific numeral symbols were used to represent one drachma ("𐅂") and ten minas "𐅗".

In later, "classical" Greek, with the adoption of the Ionic alphabet throughout the majority of Greece, the letter eta had come to represent the long e sound while the rough aspiration was no longer marked.

[3][4] It was not until Aristophanes of Byzantium introduced the various accent markings during the Hellenistic period that the spiritus asper began to represent /h/, resulting in the spelling αΌ‘ΞΊΞ±Ο„ΟŒΞ½.
