You guys must have missed this earlier thread on it a month ago... don't worry so did I... but some ... including myself... have been responding there.
Might find some interest in it.. so here is link to that thread.
NGC just sent out an email on this find. 700 Civil War Era gold coins found in a Kentucky Corn Field? https://www.ngccoin.com/news/article/11795/kentucky-hoard-civil-war-coins/
Some of the double eagles were 1863 dates. Civil war dated gold was used for payment for war supplies and most were sent to Europe. Whoever buried those coins had some real clout to even be able to obtain those with a war going on.
