Governments tend to honor certain institutions or principles through symbolic illustrations on currency.
The institution of slavery was the machine of the southern economy. It is honored in the currency illustrations of the time.
The Southern state's governments and by extension the corporate business interests of the South needed slavery to maintain it's wealth. The roots of the war at the corporate/political level was a fight to preserve slavery.
The average confederate soldier was a just a pawn.
I remember buying notes similar to the middle photo at the Army Surplus store in Huntsville as a kid. I don’t recall what we paid but it was pennies. I understand that those same notes are now worth a lot!
However, the currency I own is different than yours, so I suppose that your conclusions would simply be personal rather than factual.
You said: “The roots of the war at the corporate/political level was a fight to preserve slavery.”
In January of 1861, the states of the deep South had completed their secession. Within 30 days they had established their Constitution, laws, and court systems.
Offshore and interior trade was progressing uninterrupted. Ships from New York and Boston were docking in Charleston and New Orleans. Banks were open, goods were being harvested, and investments were being conducted.
There was no war.
Two sections were prospering.
April, and with Lincoln now in office, Federal ships appear off Pensacola and Charleston to forcibly dock.
They did not appear without orders from the very top.
They were stopped. Lincoln then called up state militias and ordered a blockade.
The evidence all points to the “root” of the war as being in Lincoln's office.
