Neat find, but not real. It's for production of custom-printed advertising pieces and used by multiple companies for promotional purposes. Note that it says "FAC-SIMILE" and "COPYRIGHT APPLIED FOR".
I believe it's this one, produced by H.M. Crider & Co. in the 1960s.
you can see at the bottom center it has the word "facsimile" spaced with the numeral 10 in the middle. I would imagine it was made in the 1930s to produce souvenir Confederate money. Who it was made for is another mystery though.
edit - I was typing my reply as Red Coat was giving his reply. LOL. He's spot on
