'Thasos type' coinage from Thrace: https://www.academia.edu/6144182/Celtic_Thasos_Type_Coinage_from_Central_Bulgaria
Very interesting indeed. Thank you for posting. Do you believe these barbaric issues were a response to the collapse of the Seleucid Empire and the demonetization of its coinage?
It seems to have been more a general rejection of classical culture during the Roman conquest. We can trace the process of 'barbarization' of these coins during the Scordisci Wars of the late 2nd/1st c. BC: http://balkancelts.wordpress.com/20...matchstick-men-the-art-of-the-scordisci-wars/
