I have some sort of hunderd dollar bill dated march 10, 1863 from the state of Louisiana. I can't find any information in any books. Trying to figurere out exactly what I got

I believe what you have, is unconstitutional money! Unfortunately, that is what we all use these days, and it is the very reason why a twenty dollar gold piece is worth upwards of $1500. Based on weight alone! Article 1, Section 10, Paragraph 1 of the U.S. Constitution says, "NO STATE ... shall make any thing but gold or silver coin a tender in payment of debt." It may be valuable as a collectors item, but I don't think you can get a bank to exchange it for cash as an official banking transaction.

Infoguy! Good info - but the op isn't asking if they can exchange it, they just want some info on it! Sheesh!
Cnhbaby - I found this link for currency issued during the Civil War, do any of these images match what you have?

(I tried to agree with you on my own post in the comments area because I'm a brainiac.. )
