Which two U.S. presidents appeared on "Greybacks" (money) of the CSA, Confederate States of America?

The Confederate States of America issued paper money worth approximately one (1) billion dollars during the Civil War. It was more than twice the amount circulated by the United States. While it’s not surprising that Confederate President Jefferson Davis and depictions of slaves at work in fields appeared on some dollar bills, so too did two Southern slave holding U.S. presidents whom Confederates claimed as their own. President George Washington appeared on a $50 and $100 bill; President Andrew Jackson was depicted on the $1,000 bill.

The Confederate currency was not backed by any hard assets; it was simply backed by a promise to pay the bearer after the war on the prospect of a Southern victory and independence.
