Ironically, as a strong proponent of sound money (as in ‘sound as gold’) he was, Jackson’s face was put on $20 bill in 1928. Back in the day, $20 was effectively the same as a one-ounce $20 coin (well, technically, 1 ounce price was $20.63).
And that fact was clearly stated on the face of the IOU note, as you can see for yourself:
But the irony hasn’t kicked fully in until 1933, when as the result of FDR gold confiscation and following dollar devaluation to $35/ounce, it has loss nearly 63% of purchase power overnight. And it was only downhill since. Today, it would take 60+ of these pieces of paper to get you same one-ounce coin
And now, I am sure, Jackson is laughing up in the heavens observing how his face is being replaced with a picture of some neo-liberal darling, finally getting removed from the piece of paper, that represents everything he was opposing strongly all his life.
