Of the lost city of Helike (Ελικη) there are remained also two coins (pictures: https://www.wildwinds.com/coins/greece/peloponnesos/achaia/helike/Traite_831.jpg and https://www.researchgate.net/figure/a-Bronze-coin-of-Helike-obverse-early-fourth-century-BC_fig2_346035801).
These coins have an inscription that should be read from the right to the left, then rendering ΕΛΙΚ.
I wondered, whether writing this retrograde on a coin was usual in those days.
