Help with this two coins

Both bought more for the challenge of figuring out what they are than anything else... Didn't pay much for them...

Roman? Diameter 29mm, thickness 2.7mm, weight 16.0 gr, coin alignment


Ferdinand? Diameter 29mm, thickness 2.0mm, weight 11.9gr

Thanks! Alex.

Hello,

The second coin is from the Kingdom of Naples; a 3 Tornesi coin of Ferdinand IV:

First one possibly a Copper Antoniannus of Maximilliam Thrax or Maxentius (Some 3rd emperor), from the time of troubles when most coins were really debased silver, billion, brass or copper.
