1909-O Indian Half Eagle. AU-50 (PCGS).We are pleased to offer multiple About Uncirculated examples of the key date 1909-O half eagle in this sale. The present example in PCGS AU-50 is warmly and evenly patinated in rich honey-gold. Otherwise boldly defined, the O mintmark is faint, yet discernible with patience even to the unaided eye. It is an attractive half eagle that is sure to find many willing bidders among 20th century gold enthusiasts.From the Boston Old City Hall Collection.
