Here is a Probus antoninianus 276-282 AD, Caracalla denarius from 198-217 AD, and a Julia Domna denarius (obverse only) from 193-217 AD. The Julia Domna came to me already slabbed ANACS extra fine (with somewhat cloudy slab unfortunately). I am considering having the Probus and Caracalla graded/slabbed by NGC. The detail that the ancient mints were able to attain on coins is amazing to me.
