Help for identifying Roman coin

Diameter 27mm

Height 3mm

Weight 17.92 gram

Some online search brought me to a Sestersius of Elagabalus (RIC IV.2# 327), the weight seems to be a bit below the known values. Can someone verify my determination? Thx :)

Thanks for the help. 326 doesn't have the star on the reverse side however (right side, but maybe not so clear in my scan).
