Several missing US banknotes [solved]

I watched a video on rare US banknotes and I was only able to find the last banknote featured in the catalogue.

As I scrolled through Wikipedia reading about the banknotes I noticed several others that I wasn't able to find in the catalogue.

The video in question

Wikipedia: Large denominations of United States currency

I also only found the $1 and $2 notes of the 1869 rainbow series in the catalogue, but they went all the way up to a $1000 banknote

I will try to list the banknotes I couldn't find neatly in this post later if I have time

Banknotes featured in the video:

$50 1869:

$100 1869:

$1000 Silver Certificate 1891:

$100 Silver Certificate:

$500 1862:

$500 1869:

$1000 Watermelon note 1890:

A coin, a banknote or a piece of exonumia is missing in the Numista catalogue: what can I do?

Thanks!
