1850-O Liberty Seated Half Dollar. WB-7. Rarity-3. MS-62 (PCGS).Iridescent reddish-russet and silver-lilac toning is seen at the peripheries of this smartly impressed, satiny example. Although scarce in an absolute sense, the 1850-O is one of the more readily obtainable New Orleans Mint half dollars of the Liberty Seated design. The present example is equally well suited for mintmarked type purposes or inclusion in a specialized collection.PCGS# 6265. NGC ID: 24HH.From the Steve Studer Collection.
