3 Coins

The pics of the reverses for #2 and #3 are upside down.

#1: Geta as caesar (obverse legend P SEPT GETA CAES PONT), reverse type VICT AETERN, Victory hovering holding wreath over shield. Wildwinds page.

#2: one of a varied series of coins from the Roman city of Viminacium, a Danube River frontier garrison town. Gordian III is the most common ruler on these coins, though this one is somewhat cruder than many of the examples on the Viminacium Wildwinds page. It looks very crude; it's either a copy, or been badly corroded and/or harshly cleaned.

#3: Nero indeed, a famous and popular type depicting the Temple of Janus, whose doors were only closed when the entire Empire was at peace. Given the size comparison with the Viminacium coin, this is probably an as. example on Wildwinds.

And speaking of Wildwinds, they have an excellent partial inscription search page that can help identify a coin where only part of the lettering is readable. Just type in the letters which you can read, and it tries to match them up with examples in it's database.

Thanks to sap pointing out that the reverse is upside down, I see that it is one of the Viminacium series. I can just make out AN X?, I'm also just able to make out what appears to be some of the lettering on the obverse, which leads me to think that it is IMPCAES C MES DECIVS PF AVG. Would make the this a coin of Trajan Decius. 249-251 AD. You are in a rich area for ancient coins, digs are turning up sites all the time. Most of the uncleaned lots come out of this are.

The page at WildWinds says that the Geta's coin is a denarius. Doesn't that mean it is made of sliver and as such should be all silvery and not so dark as mine?

Thanks for telling me. As for the cleaning I saw on several places that people recommend not to do it, so I shan't.
