Caria. Uncertain Mint. 5th century BC. Hemiobol, 0.28g. (7h). Obv: Head of lion left, mouth open and tongue protruding. Rx: Knucklebone. Apparently unpublished in the major references; cf. SNG Keckman 837 ff.; SNG Kayhan 941 ff. VF.
Although playing knucklebone (astragalos) was a popular pastime in ancient times and several coin types refer to this game, this combination of roaring lion with knucklebone seems to be unattested in the primary references.
