This is a 1811/10 Capped Bust Half in PCGS AU50.  Herrman and the Bust Half Nut Club give this O102.2 marriage an R4 in Rarity.  The other 1811/10 die marriage is O-101 and it is considered R1.  So the O-102 is far less common.  In fact, Herrman lists only 3 AU/CAC examples that have been auctioned from 2017 to 2025.  The most relevant (within the last 3 years) is an AU55/CAC in a Sheridan Downey auction that went for $4462 in January, 2025.
 
This example is largely enveloped in khaki gray and russet tones with highlights of aqua blue and amber.  Scrolling between the two images above shows how the rich luster rotates through under the light.  There are no major detractions on this pq and hard to obtain example.
 
This coin is approved by CAC.
