1909-O Barber Dime. MS-66 (PCGS).Lustrous surfaces are splashed with mottled olive-gray, cobalt blue and medium rose patina that is more extensive on the obverse. Sharply struck throughout, and uncommonly so for the issuing mint, this conditionally scarce Gem represents a significant find for the advanced specialist in New Orleans Mint and/or Barber coinage. The historic 1909-O is the final dime produced in the Louisiana coinage facility. Despite a mintage that is nearly twice as large (2,287,000 vs. 1,789,000 pieces), this issue is rarer than the 1908-O in all Uncirculated grades. More challenging to locate than the 1892-O, 1893-O, 1905-O, 1906-O and 1907-O, as well, the 1909-O is sought after at all levels of Mint State preservation.
