Das System der kaiserzeitlichen Münzprägung in Kleinasien (Berlin, 1972). Kraft proposed a system of traveling workshops to explain the similarities. For example, he considered this coin of Laodicea ad Lycum in Phrygia to have been a product of a traveling workshop he called the "Sardis Workshop." Philip II as Caesar, AD 244-247. Roman provincial Æ 25 mm, 7.7 g. Phrygia, Laodicea ad Lycum, Sardis Workshop, AD 244-247. Obv: •Μ•ΙΟVΛΙ••ΦΙΛΙΠΠΟϹ•Κ•, bare headed, draped and cuirassed bust of Philip II, right, seen from front.

Note, for example, the similarity in artistic style, the subject matter of the reverse types, and fabric between the coins of Antioch in Pisidia and those of Parlais: Julia Domna, AD 193-217. Roman provincial Æ 21.3 mm, 5.15 g, 7 h. Pisidia, Parlais, AD 193-196? Obv: IVLIA-DOMNA, bare-headed and draped bust, right.

There could have been a central common mint to which cities contracted their minting needs. Dies could have been lent or sold from one city to another, and so on. This new work, Connections, Communities, and Coinage: The System of Coin Production in Southern Asia Minor, AD 218–276, by George Watson, is reviewed here in Coins Weekly and refutes Kraft's arguments. The book sounds like a worthwhile acquisition for numismatists interested in the Roman provincial coins of Asia Minor.
