This
Antoninus Pius sestertius appears to have been made into a proto-contorniate and then (possibly later) holed.
Interestingly, the
rim (which was difficult for me to photograph clearly), which was hammered like all proto-contorniates, has a stamped or incised
like pattern on it. I am not sure how common this is on photo-contorinates - my other ones all have smooth edges.
Antoninus Pius,
sestertius,
Rome, circa 140-143 AD.
