COIN (ROMAN)
Probably a contemporary Roman bronze copy of a silver Republican denarius.
    The size suggests a Roman Republican denarius as does what looks like a bust of Roma facing right on the obverse. The metal, however, suggests that it is a contemporary copy (possibly the core of a previously plated imitation). The rough and pitted surface and crude style of the horseman support this theory. 
     
    There are several denarii that sport similar designs - Crawford RRC 286/1 and 295/1 (116 or 115 and 113 or 112 BC respectively) - the latter even has a large Q behind the horseman that maybe preserved here.
