Constantius II?

Hi Saxdiva,

Your coin is actually Constantine the Great minted at Thessalonica and struck in 324AD.

Attribution

Constantine I - Thessalonica Mint - AE3 - RIC VII 123

Obverse: CONSTAN_TINVS AVG, Laureated head right

Reverse: D N CONSTANTINI MAX AVG, Laurel wreath enclosing VOT/XX with TSepsilonVI in exergue

Here is another example below that shows a clearer mint mark.

Yours looks real to me. Late Roman bronzes aren't usually counterfeited, so you generally don't have to worry about fakes when buying them.

very nice portrait,it remeber me a great costanitne's head I saw in Rome....

Very cool, and thanks so much for all the info. No wonder people get so addicted to this--it's mind-blowing to look at a coin that's nearly 1700 years old.

I guess old coins are another of those things that you don't really OWN, you just take care of them for the next generation. :-)
