Description

1724 Hibernia Halfpenny Pattern, PR40
M. 9.2-P.1, Famous 'Neptune Reverse'
Only Four Examples Known

1724 1/2 P Hibernia Halfpenny Pattern, Neptune Reverse, M. 9.2-P.1, High R.7, PR40 PCGS. Ex: Appleton-Boyd-Ford, Sydney F. Martin Collection. Deep mahogany fields contrast with walnut-brown high points. A circulated but problem-free specimen of the so-called Neptune Reverse pattern halfpence for the Hibernia series. Just four examples are known; the others are respectively pedigreed to Farouk-Norweb-Martin, Garrett-Roper, and Robison. The presence of a trident explains the Neptune Reverse name. Sydney F. Martin assigned the variety 9.2-P.1, die linking the obverse to 9.2-Nb.1, which has a more familiar Hibernia reverse motif. The Neptune Reverse design dates at least to a 1628 pattern shilling by Nicolas Briot, intended to honor the English Army and Navy.
Ex: William Sumner Appleton Collection (Charles Steigerwalt, 5/1907), lot 734; F.C.C. Boyd; John J. Ford, Jr. Collection, Part VII (Stack's, 5/2005), lot 94; Sydney F. Martin Collection (Stack's Bowers, 8/2024), lot 6106; Dallas Signature (Heritage, 12/2004), lot 3001.
