It's fake. Replica. Back side lower left says facsimile

I own one of these as well. It is basically ensuring that the note will be legal tender once the South won the war. Since this never ended up happening and the signs were looking dire after Gettysburg, many began disregarding them near the last years of the war, causing massive inflation.

To expand a bit on /u/a_sage_chair's answer, note the other text on the bill: "The Confederate States of America will pay TEN DOLLARS to bearer"; that is to say, you can exchange it for a certain amount of gold. The CSA (and the USA, and practically everyone else in the world) were on a gold currency at the time: The bill is not "really" money, but it can be exchanged for "real" money and is much more convenient to carry around. But because the Confederate government needed its actual gold reserves, such as they were, to pay for guns and whatnot, their paper money had the hedge; "you can get the gold, but only two years after the war ends". The US chose instead to suspend payment in gold entirely, and issued "greenbacks", which were not redeemable for gold. These are both financial methods, ie accounting tricks, to mobilise the real economy, consisting of loaves of bread and young men.

I'd like to see photos just for the sake of seeing such a cool peice of history.

Is 'obverse' a fancy way to say 'front'?
