I don't know. It's an 1860 and Civil War era stuff has broad appeal. I could easily see anything from that period being in demand and commanding a big premium vs similar items from other years. 

Congratulations on your new coin as mintages may not always be a guide to rarity.

I just picked up a 1814M 15 soldi for my Napoleon collection and this has a mintage of just 371 however the 1809M issue is much rarer even though the reported mintage is much higher at 14,858.

I suppose the 1809M got a lot of use as it was struck early on and the 1814M coins were saved as Napoleon's empire was in collapse at the time.

Hello John. Very choice au half eagle  in an older slab. Strong for the grade too. I love all Liberty gold 1840-1907. In all denominations. My focus has switched to the Eagles from the New Orleans mint. Just posted my 1860-O $10  Have to take new pics and post all the rest of the coins. My coin count in the Liberty Eagles is about 22. Little over a dozen from New Orleans. 
My last visit here was pre pandemic. PCGS coins were not allowed then. Now they appear they are. Still lacking well over a dozen N.O. Eagles Presently.

  Labor of love I say.  

And much patience... 

I look forward to looking at your 1860 mint set and others. Thx for sharing this nice piece of gold! And good luck in your quests
