1772 Machins Mills Halfpenny. Vlack 24-72C, W-7740. Rarity-6. GEORGIVS III. Good-6.103.3 grains. Smooth, even wear and light coppery grain defines this rare Machins Mills halfpenny, one of the more recent die pairings to enter the canon for this series. Legends are weak to nonexistent, as always seen, even on high grade survivors. Here is a new specimen to the census for the Vlack 24-72C pairing, recently discovered by our consignor in a group of otherwise mundane world coins.
