King Ziailas of Bithynia is only known from this limited series of coins.
The third king of Bithynia after Nikomedes I, and only the second to strike coinage, little is known of his reign and those scant details we have are from the very few bronze coins such as the present piece that have been found to date.
Unlike his predecessor who is known to have issued coins in both silver and bronze in several denominations, Ziailas appears to have only struck this one denomination of one type.
Extremely rare.
