In what seems to be a pattern, the city of Eleutheria is known mostly from its rare coinage, with the exception of a single mention in a 6th century BCE passage by Stephanus Byzantinus. The Barrington Atlas doesn’t list the city, so we pretty much have no idea where it was except that it was in Mysia.
The coins depict Athena, though not in the same style as Athens. The reverse, with a lion, is more becoming of the area.
Interestingly, these coins are available through various dealers, but are almost never listed at auction.
