1824 Capped Head Left Half Eagle. BD-1, the only known dies. Rarity-5+. Genuine--Plugged, Damaged (NCS).This single die marriage issue, as with all in the challenging Capped Head Left half eagle series, is elusive in all grades due to widespread melting. From a mintage of 7,500 to 17,340 pieces, survivors of which are thought to number only 30 to 40 coins (these estimates per John W. Dannreuther, 2006). <strong>Good Details</strong>.
