Almost all in my hand have something like a stamp

 

[Mackaydon]

"TI.C.A." on As size coin, countermark likely from Claudius, often on coins found in the Moesia Region (Bulgaria), similar to the countermark found on certain Caligula Asses in the Rhine region. The countermark may also be from Titus (Titus Caesar Augustus).
