I think the dots were used as centering devices, one see them sometimes on Soldiers/Standards coins although on this coin it is certainly a large dot.

Mint: Rome

The Roman Moneyers (or you may prefer the title of Mint Magistrates) were also responsible for the minting of gold, silver and bronze coinage and they reported to the Senate. They were known as the Triumviri Monetales or Triumviri Auro, Argento, Aeri, Flando, Feriundo which is abbreviated as III VIR. A.A.A. F.F. which may be translated as 'Commision (or college) of three men under whom gold, silver and bronze coins were struck'. (Note that the order of the metals varies according to different references.) The title 'III VIR. A.A.A. F.F.' occurs rarely on Republic coins and when it is present it is usually seen in an abbreviated form such as 'III VIR'. It is interesting to note that the full title occurs frequently on the reverses of Augustan Aes

The College of the Three Moneyers was a revived republican tradition. This coin was struck under the supervision of Marcus Salvius Otho, an ancestor of the future emperor Otho. Later, the number of members was increased to four, and their names were not included on the coins.

TRP = This is short for tribunicia potestate - "with the power of the Tribune of the Plebs." The government of Rome was split into the Patricians (who were Senators) and the Plebians. Nine Tribunes of the Plebs were elected by both Plebs and Patricians every year to be in charge of the Plebian assembly. These Tribunes could not be injured because it could be punishable by death. They had veto powers, and they could prevent a law from being passed or an election. An emperor cannot technically rule on the Plebian assembly since he is a Patrician, but by taking the title he could be free from injury. On a coin, if this symbol is followed by a number, it depicts how many times he has been elected Tribune of the Plebs.
