Note: The governor Statius Longinus was the first to issue coins for Macrinus at Nicopolis ad Istrum, so his coins for Macrinus and his son Diadumenian would fall at the beginning of Macrinus' short reign.
For more information, see Pat Lawrence's die study on her page "The Longinus Dies for Macrinus and Diadumenian at Nicopolis ad Istrum." This page includes many interesting and attractive examples, including specimens of the same obverse and reverse die as this coin. They are listed by Pat as obverse DBc and reverse R7viii.
