As the title says, this is a 1963A $20 Federal Reserve Note which, from my non-expert examination
(going by what the PMG website says) appears to be in the AU category.

If you look at the photos, you can see one slight crease down the middle of the bill, but even with this crease, the bill is
still very crisp, and the clarity of the ink is remarkable.

I have not had this officially graded, so you will need to examine the photos to make
a judgement on the item.

The price may seem a bit high, but I will consider any reasonable offers.
