RIC doesn't list a coin with the
legend CONSTANTINVS
IVN NOBC for SMH gamma dot (there is one listed for dot SMH gamma dot) There is a coin listed for the
legend FL
IVL CONSTANTIVS
NOB C for SMH gamma dot, so since both legends (CONSTANTINVS
IVN NOBC and FL
IVL CONSTANTIVS
NOB C ) are recorded for dot SMH gamma dot, it makes sense to find both legends for SMH gamma dot. So, succinctly, your coin is not listed in RIC.
