U.S. Dollar Typeface? Help please :)

Does anyone know the typeface used on the back of U.S. Dollar Bills?
The typeface they use to write on the back of the bill for example, "Fifty Dollars" ?

I would greatly appreciate it! Thanks :)

It's custom engraved, but Federal is close.

Archive Garfield is somewhat close as well, but has a very specific look to it.
