This coin is not in RIC for PLG•; though the footnote for 153 says "In L(ondon) 3 specimens..." one with the same mintmark as this coin and also VOT/IS/XX; though the reverse legend is broken as TRA-NQVIL-LITAS. By having it in his footnotes, Bruun seemed to think it was probably irregular and my coin has an unusual bust, so probably unofficial in really nice style.
