In reviewing pics of my first century bronzes (mostly As & Dupondius) I notice one other 'minor' detail.
The flan crack !
Flan cracks become common in the later 2nd century and practically the norm by the 3rd century. This was caused by the recycling of older coins (erasing the past) and the inadequate addition of 'fresh' copper.
Copper like silver is very malleable. Flan cracks are also often cited as evidence of authenticity. In reviewing my collection I find only one first century bronze with a small die crack. It is a provincial Vitellius that was no doubt made from recycled coins (probably of Nero !)
Of the official coinage zero flan cracks.
I cannot help note your picture shows a crack.
Again not definitive ........ but reason to wonder
