Undated (ca. 1652-1674) St. Patrick Farthing. Martin 9a.1-Fc.10, W-11500. Rarity-7. Copper. Two Annulets Below King. Very Good, Surfaces Smoothed.73.5 grains. Warm medium brown patina dominates the in hand appearance on both sides, the upper left obverse with a broad swath of antique gold from a brass plug centered to the left of the crown. The strike is well centered on the planchet, the borders worn down into the peripheral devices somewhat, but all at least partially discernible, including the top of both annulets below the king. Central design elements retain partial outline detail, the surfaces lightly pitted with a curiously glossy texture and evidence of smoothing to explain our qualifier. A rare and interesting die pairing among St. Patrick farthings that will appeal to advanced specialists in this enigmatic and challenging series.Collector envelope with attribution notation included.
