1788 Machins Mills Halfpenny. Vlack 23-88A, W-8100. Rarity-2. GEORGIVS III, Group III--Double Struck--Fine-12 (PCGS).109.2 grains. A neat error piece, boldly double struck with the second strike 50% off center. Dark brown surfaces have just some faint underlying granularity and thin planchet flaws, but are overall glossy and decent for the grade. Two matching pairs of intriguing square marks are seen on the obverse at 6 and 9 oclock and could have something to do with the striking anomaly. Errors such as this are not at all common in the Machins Mills series.PCGS# 826967.From the Sydney F. Martin Collection. Earlier ex Richard August, February 2011.
