This 1811/10 Capped Bust Half, is the O-101, or Punctuated Date variety.  The Bust Half Nut Club considers the variety to be 1811/0.  The 'Punctuated Date' is for having a large dot at the base and between '8' and the first '1' in the Date.  This example is pedigreed to Stephen Herrman who keeps track of bust half auction prices in his published book 'Auction and Mail Bid Prices Realized for Bust Half Dollars 1794-1830'.  This example is silverly gray with a flashy cartwheel under the light and no major detractions.

This coin is approved by CAC.
