Series with COMOB mark. Variant with shield decorated with a victory facing and holding a wreath in each hand.
I followed the weight of 4.45 grs given during the last sale by Classical Numismatic Group, while the old sales gave 4.44 grs. Considering that the scale was perhaps more accurate on this date.
I note that no coin that I could see has a jewel on the diadem. There are at least 3 obverse dies and same number of reverse dies. The coin sold on 10 March 2003 par Gorny & Mosch Giessener Münzhandlung, Auction 122, lot 2305, shares the same obverse die as the coin illustrated in the RIC X, plate 15, n°349 (sources given by the RIC X: London British Museum and Kunsthistorisches Museum of Vienna, the RIC X does not specify the provenance of the photo). The coin from Gorny & Mosch Giessener Münzhandlung shares the same reverse die as the coin sold in its sale of the 07 March 2011, Auction 96, lot 3052. The coin having a different obverse die from the other examples mentioned. We find the same two dies on the copy sold on 15 June 2006 by Classical Numismatic Group, Electronic Auction 135, lot 252. Finally, the copy sold on 02 April 2001 by Gorny & Mosch Giessener Münzhandlung, Auction 107, lot 627 has dies different from all the other coins mentioned.
These coins from this mint all seem to have a spear depicted without a tip.
