Due to new scanning technology originally built to scan heavy machinery, we can now know what lost Roman emperors looked like in 3D, such as Claudius II and Tetricus I.
This scanning technique scans coins while still embedded in the ground by taking thousands of 2D images of the coins, and then use them to build detailed 3D images of the emperors on the coins.
This can be done without having to clean or dig up the coins, which is time consuming, and keeps the integrity of the Roman coins intact. It can even be used to scan through a pot of coins without ever taking them out of the pot.
