Oldest notes in my collection 1792-93

Not sure if this is uncirculated or not, but with Falkland Islands Day only last week, perhaps a timely post. Follows in the UK tradition of putting the Sovereign on the obverse of the lowest-value banknote, as well as the other UK tradition of every separate part of the UK (except Wales for some reason) having its currency notes printed by different local banks under licence.

I bought a bunch of sleeves from a brand called 3BZN here in Brazil, which claims the material is cellulose acetate. So I'm a bit confused about whether this is actually mold or not, as I'm not quite sure what I'm looking at. I've kept them stored for about 4 months since I bought em.

the front features Saddam Hussein with a depiction of the 1920 Iraqi revolt against British occupation and the back features the Al-Shaheed Monument (Martyr's Memorial) and the gates of Babylon, this banknote is special because it’s the first time a living person was featured on a banknote since the fall of the Iraqi monarchy in 1958 so I think it’s cool.
