Gladiators Of Rome Help

My opinion is that this coin isn't from Rome, but rather Greece (Elymais specifically). Compare yours to the one in this acsearch link:

The coin you have pictured is not Roman, as note by Spence. An actual "Gladiators of Rome Bronze Centenionalis Coin of Constantius II" would look like this: https://www.ebay.com/itm/393350401806

Using "gladiators" to sell such coins is just a marketing gimmick, and the wrapper in the ebay link I just gave is from a mass-marketing coin dealership that doesn't actually convey much of the important information you'd want to know about this specific coin - such as catalogue reference numbers, or even that the mintmark is TSE (Thessalonica). The advertising blurb is actually quite wrong, in that a centenionalis does not "depict the exciting end of a gladiatorial contest" but rather depicts Rome symbolically spearing Rome's Parthian enemies on the battlefield. The soldier on the coin is in full Roman battle armour; Roman gladiators rarely dressed up as actual soldiers - gladiatorial armour was designed for spectacle and bloodshed, rather than for actual practical military use. Gladiatorial depiction on coinage is excessively rare, and when it does occur, it's normally quite obvious. http://www.wildwinds.com/coins/rsc/didia/i.html

I've also never heard of Constantius II being particularly fond of gladiatorial combat; it's not mentioned on his Wikipedia page. That entire blurb reads like something a keen but clueless AI would write.
