Ah, second one is definitely a reproduction then (#40674). However, I'm not positive about the first, serial #39669. The ink is brown, which according to that link is a good sign. I just don't know why one of those bills would be real and one would be fake. I found them both together.
The reverse of the second one has me suspicous...my eyes are not what they once were even though your images were a modest size.
There have been many reproductions of these notes. I am by far not an expert on Confederate notes but I have looked at enough of the real ones to write this. There are several folks here that may have additional info for you as well. The 1st note appears to be an 1864 issue note as well as the 2nd, however, the 1st looks real.
Thanks for sharing these.. the 1st one looks real to me.
