USA (New Orleans mint), half dollar Seated Liberty, 1861-O, Louisiana issue (die W-08), from the SS Republic (1865), encapsulated NGC Shipwreck Effect. KM-A68. Very light surface corrosion on about 80%, the rest lustrous. The so-called "Louisiana issue" of 1861 (detectable from minute die details) refers to coins struck in just one month (February) when the mint was under State control before operating under the Confederacy. While therefore popular, these "Louisiana issue" pieces were actually struck in greater quantities than the previous US issues and the later Confederate issues for the same date. From the SS Republic (1865), with certificate from the salvagers.
Estimate: $600 - 900
