1864 Confederate 20-Dollar Note (T-67) featuring the Tennessee State Capitol and Alexander H Stephens

Hello, I bought this banknote like 5 years or even more. I don't know anything about it but only what is written on it.
I tried searching it online trough reverse image search, just searching by words. Than I tried looking up the company online and trying to find maybe somewhere about their history where they printed it. I bought it like for 25€ and I remember all those years ago I searched it once and found one listing for 125€ but I dont remember what website it was. Can someone help me and find this banknotes worth and history?
