Got this one in an ebay lot almost two years ago, and it's been a real stumper. Can't tell if it's a degraded copy of the CONCORDIA AVGGG type, but there is a -VO- in the legend. I think only Hilderic issued a cross nummis with a left-facing bust, but this one is clean shaven and in the wrong style.
Measures 8x9mm and 0.59g
