1905-O Barber Half Dollar. AU-55 (PCGS).Splashes of moderate toning adorn both sides of this overall boldly defined, partially lustrous example. As with all New Orleans Mint issues in the conditionally challenging Barber half dollar series, the 1905-O is scarce to rare in all but the lowest circulated grades. Indeed, this is an uncommonly well preserved survivor from a limited mintage of 505,000 pieces.
