"Milled coinage" - struck by machine, such as a water mill or screw press, rather than hammered by hand.
There are
plenty of coins worldwide where the
Roman model is emulated. Certainly the concept of the side-view
portrait of the reigning monarch in regal pose (often wearing a
laurel wreath), surrounded by the monarch's titles, is widespread throughout the coinage of Europe.
The gold "augustale" or "augustalis" shows clear evidence of
Roman inspiration even in mediaeval times; apart from the lettering, these coins "look
Roman". Obviously Holy
Roman Emperor Frederick II, on seeing some ancient
Roman coins, told
his mint workers in
Sicily to go and do likewise.
Here's an example in the Kunsthistorisches Museum
Vienna:
