I Roman (pre Constantine?) and 1 either Greek or fake Larger scans now attached

Ok, your challenge...help me identify these two.
The darker (Roman) is about 18MM and weighs 3.4GR
The more silver color is about 16.5MM and weighs 4.1Gr
Neither is magnetic.
Thanks for your help!

Silver deniarus is either early Imperator or late Republican

The silver denarius is:
 MARK ANTONY Denarius (32-31). Obv: ANT AVG / III VIR R P C. Legionary galley right. Rev: LEG XV, legionary aquila between two signa.
If this is a genuine silver denarius it is in quite good condition for this type - this type is sought after and can easily be sold on ebay or at auction. It is made just before Mark Anthonys clash with Octavian at Actium where Octavian won, ending the triumvirat and becomming the first and one of the best known emperors (he is also known as Augustus). Marc Anthony commited suicide.
I need a better picture to identify the other coin.

Thanks for the help Brian!
