1826 Capped Bust Half Dollar. O-106a. Rarity-2. MS-63 (PCGS). CAC. Exceptionally attractive toning blankets both sides in rich steel-blue patina and lighter mauve and golden-orange iridescence. Lustrous surfaces are sharply struck and far smoother than one might expect even at the assigned MS-63 grade level. Writing in the Autumn 2021 revision to his <em>Auction & Mail Bid Prices Prices Realized for Bust Half Dollars: 1794-1839</em>, Stephen J. Herrman provides a Condition Census list for the 1826 O-106a die state that ranges from MS-63 to MS-66. This newcomer to the modern census qualifies for that distinction, confirming its desirability for an advanced Bust half dollar set. From the Abigail Collection, Part II.
