My latest Roman acquisition, from my local dealer. A common enough type, but much better condition than most of my collection.

Obverse: Emperor Caracalla, ANTONINVS PIVS AVG BRIT
Reverse: Liberty standing, holding the pileus (liberty cap) out in front of her while leaning on her staff. PM TRP XVI COS IIII PP. The reverse legend gives sufficient detail to enable this coin to be accurately dated to 213 AD.
It may seem a bit incongruous to us today, particularly to Americans, to see Lady Liberty and one of your more despotic Roman Emperors sharing the same coin. But remember, Rome was still theoretically a Republic.
Listed in Sear (millennium edition) as #6830, apparently in RIC as #209a.
