This appears to be a TI.C.A
countermark or more likely a degraded imitation.
Host coins of TICA cmk are, among others,
asses of Gaius,
Germanicus and
Agrippa.
A wide group of coins bearing this cmk is however very worn and the second
face is blank and flat, without any sign of the original
legend or personification.
Weights are in the range between 3 and 7 grams. Letters are not well defined. Sometimes the cmk appears to read II.C.A instead. Some appears even to be
cast.
It is believed that this group of coins are imitations that were produced just punching a blank
flan in order to vehiculate the cmk.
Attached one of mine: 21 mm, 4.1 g.
