This coin from the Greek colony of Cherronesos is the single most common of all early lion coins, It features on the obverse the forepart of a lion with tongue sticking out and looking backward, and on the reverse a four-part (quadripartite) incuse square consisting of two raised quarters and two lowered quarters, typically adorned with mint symbols on the two lowered quarters. These coins are typically described as the lion facing one direction with its head reverted, though if it's facing that direction and as its face is part of its head. The lion's curving body, tucked-in front paws, and head turned completely backward are abstracted renditions of reality that permit the design to aesthetically, and strikingly, follow the curvature of the coin. With well-preserved specimens, the lion's mane is marvelously detailed, despite the coins' small size, and the lion's body is clearly demarcated into chest, midsection, and hind quarters. Another attractive feature of these coins is the plethora of reverse symbols, which include but aren't limited to a pellet, cicada, scorpion, tunny fish, flower, torch, trowel, ram's head, caduceus, rooster, bee, wine leaf, bucranium, conch shell, scallop shell, dot in a circle, boar head, pileus, plow, sunburst, club, bow, and helmet. These coins are sometimes described as being from Tauric Cherronesos or Tauric Chersonese, "Cherronesos" (also spelled "Cherronesus," "Chersonesos," "Chersonesus," and "Chersonese") is the Greek word for "peninsula," and there were no fewer than 28 geographical areas referred to in the ancient sources as "Cherronesos." Thracian Cherronesos, which today is called the Gallipoli peninsula and is part of Turkey, is the peninsula in the northeast Aegean Sea on which the cities of Kardia/Cardia and Lysimachia were situated.
