I have had these and bunch of others since I was a kid. Pretty sure they are fake. I have some real ones that are normal currency paper, but this stuff has a waxy feel to it, not like a normal bill. I take it these are fake?
It's more of a hard feeling to the paper. Almost like the paper was coated in a light wax. Let me ask a question. Are there any old bills like this that have that kind of texture?
I second the motion as we get these brought in at work and get phone calls about them as well. I always comppare them to parchment paper. The real stuff is closer to tissue paper.
Another diagnostic on confederate paper that I have often heard was that the signatures on the real notes were done with an ink that bled thru the paper, I know this because my father had bundles of repliconfederate notes and did some research. My brothers wife took them and frames them and sells them at flea markets and swap shows. They also have websites that note often copied serial numbers of these notes.
Maybe this will help. Here's a site that has a list of fake CSA notes. http://www.crutchwilliams.com/BogusCSA_RoTx.html Lou
