Wasn't there a Dukes of Hazzard episode where they chased after like a million dollars and then discovered it was confederate money? Pretty cool piece of antique Americana though.

Interesting that technically President Lincoln only outlawed slavery in the "Non Border States" with his emancipation proclamation. So there were (on paper) states flying the stars and stripes that allowed slavery whereas the confederate states (on paper) had it outlawed.
