Not bronze, but it’s still a neat campgate. It celebrates a victory against the Sarmatians, who would not be DEVICTA until Constantine handled it. The turrets have eagles on them.
What I thought was interesting was that this coin ended up on eBay and the route it took. The first auction listing I found for it was 2012 from Lanz where it was unsold with an 800 EUR estimate. The next auction was Gitbud & Naumann in 2013 where it sold for $710. The last auction was Gadoury in 2015 where it sold for $753. On eBay, in 2020, it only sold for $376.55…how the mighty have fallen!
