I found this mysterious denar, S.Severus or Caracalla, worn piece, but it seems to me that someone tried to write something on obverse and reverse..Weight is 3 gr..
FF02, the whole coin is very precisely cut around..I have never seen anything like it before..And the coin is 2.2o gr., my mistake...
LOL. Better than my guess, that it's Runic, proving that the ancient Teutons and Vikings got as far south as that.
