Do I Have A Rare Aurelian ?

Both your coin and the VCoins example are RIC 248 in my opinion. Interestingly, RIC lists Cohen 142 as the type examplar for both RIC 135 and RIC 248! Cohen describes Sol as standing neither left nor right but as "standing facing, looking left", which indeed is the case. The difference then, must be one of style alone. In the introduction to Aurelian in RIC, Webb mentions that at Siscia (e.g. 258), the portrait is "unpleasing" and the neck is "often too long" (p. 258), while portraits at Mediolanum (e.g. 135) are "well-designed".
