Undated (ca. 1652-1674) St. Patrick Halfpenny. Martin 5-F, W-11540. Rarity-6+. Copper. Reeded Edge. Very Good.130.6 grains. The obverse is more heavily worn than the reverse, the former side approaching Good details, the latter close to Fine. The king, crown and harp are only partially outlined, peripheral lettering on the obverse nearly absent, faint remnants of the brass plug centered over the lower left corner of the crown. On the reverse we note bold outline detail to most major design elements, the impression off center to 1 oclock with the peripheral lettering along the upper right border mostly off the flan. Light to moderate pits are most prominent on the obverse around the kings head, the surfaces predominantly smooth in hand with dominant toning in pleasing golden-brown. Martin 5-F is one of the rarer die marriages of the large size St. Patrick issue.Collector envelope included.
