4.86g, 25mm diameter

Obv: Bust of Claudius right, LS below = year 6

Rev: Messalina standing left, leaning on a column and hold two figures in her outstretched hand.  These figures are theorized to be Britannicus and Octavia. "MESSALINA KAIS SEBAS"

Some corrosion along the top of the obverse.  Very light weight coin.  It would seem that the copper has been leached out of it.
