R. McAlee notes that there are three distinct varieties of this type, which he suggests were struck at Antioch at different times: (1) inscription XAΛKOYΣ ΔΙΡ (see examples 1-3, 5-6); (2) inscription XAΛKOYC, with C instead o f Σ and no date (see examples 4, 7-10); (3) no inscription (see examples 11-12).The second variety was published in R. McAlee, The Coins of Roman Antioch Supplement No. 1 (2010), no. 122A, where it was dated probably to c. Year 145 Caesarean Era = AD 96/97, based on the similarity of style to the other civic issues of Antioch bearing that date. See the discussion at Supplement no. 1, no. 122A.Based on the fabric, weight and size R. McAlee would date Group 3 in the first half of the 2nd century, perhaps as part of the issue dated Year 177.
