The Tetradrachm of Macrinus (217-218 AD) is a large silver coin minted during the brief reign of the Roman Emperor Macrinus. Macrinus ruled from 217 to 218 AD following the assassination of Caracalla and was known as the first emperor who did not hail from the senatorial class. His coinage includes silver tetradrachms struck primarily at mints in the Eastern Roman provinces such as Antioch and Jerusalem.

This tetradrachm typically weighs around 12 grams and measures approximately 26 mm in diameter, significantly larger than typical Roman denarii, highlighting its status as a high-value silver denomination. The obverse features a laureate, draped, and cuirassed bust of Macrinus facing right with inscriptions denoting his imperial titles. The reverse often shows powerful imagery reflecting Roman ideals, such as deities or symbols of authority, intended to reinforce the legitimacy and strength of his short reign.

These coins are valued by collectors for both their historical significance and robust silver content. The rarity combined with excellent portraiture makes Macrinus tetradrachms desirable, especially those with good strikes and attractive toning or surfaces.

In summary, the Tetradrachm of Macrinus is a substantial silver coin from a notable yet short-lived Roman emperor’s reign. It offers collectors a tangible connection to a fascinating period of Roman imperial history and presents as a beautifully executed piece reflecting Roman artistry and power in the 3rd century AD.
