1861 New Orleans Half Dollar die varieties are very popular due to the research published by Randy Wiley in Gobrecht Journal issues #94 and #97.

Opening the #94 GJ issue with his ground breaking research article, Randy Wiley states, "Half dollars from the New Orleans Branch Mint date 1861 have a special place in the hearts and minds of many collectors as they have become a tangible reminder of the great civil war that ripped our country apart during the 19th century. These 1861-O coins are in demand not only from half dollar collectors trying to complete a date aand mintmark set, but by collectors in general who want to own a small piece of history."

Emisson Sequence

"In March, 1992, coin dealer Julian Leidman loaned me a box containing 189 circulated 1861-O half dollars that he had recently purchased. I compared these coins to 20 pieces that I already owned together with 11 other coins belonging to Bill Bugert. We had used these 31 coins as a die marriage set for the 1861-O half dollars (See The Complete Guide to Liberty Half Dollars published by DLRC Press, 1993). At that time, our die marriage reference set contained 11 die marriages from obverse dies and 9 reverse dies. I spent every spare moment I could find during the next week examining these 220 half dollars. No new dies were identified, but three new die marriages were discovered involving previously known dies. The final count was 14 die marriages from 6 obverse and 6 reverse dies. All 14 die marriages were linked through die state combinations in a continuous chain so that an emission sequence emerged for all 1861 half dollars struck at the New Orleans Branch mint...........
