Oh no, I posted the wrong photos! I am trying to sort out my images folders -- I will post the proper pics tomorrow -- I am embarrassed and sorry.
Mine is the same coin but just a bit different in style and letter spacing. I'm not familiar with the spacing on your obverse but these are out of my area of specialization so that means nothing. Both of the sons have BRIT obverse coins from the period but I do not have British reverses for them.
My only coins with "Brit" come from Caracalla CARACALLA AR Denarius OBVERSE: ANTONINVS PIVS AVG BRIT, laureate head right REVERSE: MONETA AVG, Moneta standing left, holding scales & cornucopiae Struck at Rome, 211 AD 2.28g, 19mm RIC 224 CARACALLA AR Denarius OBVERSE: ANTONINVS PIVS AVG BRIT, laureate head right REVERSE: P M TR P XIIII COS III P P, Pax running left holding branch & scepter Struck at Rome, 211 AD 3.11g, 18mm RIC 184, RSC 190, BMC 4
