1810 Capped Bust Left Half Eagle. BD-4. Rarity-2. Large Date, Large 5. AU-50 (PCGS). OGH.Vivid medium gold patina with blushes of iridescent pale pink outlining many of the peripheral devices. Lustrous for the assigned grade with overall sharp detail and strong visual appeal. The BD-4 attribution corresponds to the Large Date, Large 5 Guide Book variety of the 1810 half eagle. This is the most readily obtainable of the four known die marriages of the date and, given that it is also a plentiful variety by Capped Bust Left five-dollar gold standards, this lightly circulated AU holds particular appeal for type purposes.
