Hello! I've noticed that there is no option currently for banknotes made out of pure cotton fibre. Examples of these include:
Euro (both series)
Canadian dollar (all except the new polymer ones)
It says on the European Central Bank website "Just like the first series of euro banknotes, the Europa series of banknotes are printed on pure cotton-fibre paper, which gives them their special crispness and wear resistance. Certain security features, such as watermarks and embedded threads, form part of the paper itself."
On Wikipedia (on notes of the Canadian dollar) it says this "Bank notes were printed on paper composed of pure cotton. Cotton fibre was discontinued and replaced by a synthetic polymer starting in 2011, with the last of the synthetic Bank Notes being made available in November 2013."
I know there are likely more examples, but these are pure cotton and nothing else. These were all I could find, but I'm sure there are more.
Most paper banknotes use pure or nearly pure cotton. For example, the Bank of England https://www.bankofengland.co.uk/banknotes/counterfeit-banknotes
always used cotton until the recent switch to polymer.
I don't see the need for separate kinds of paper in the main dropdown list unless it can be shown that there are lots of notes printed on other kinds of paper. The only examples I can think of are the early Chinese notes printed on mulberry paper. As it stands, we have an extra box after composition where this could be added.

Ah, fair enough. I do suppose it isn't completely necessary, though there are different blends of materials in bills such as the U.S. dollar (75% cotton, 25% linen), but I see your point. Still though, it would be nice to have the option to specify. If not, that's fine, but it could make things that little more accurate.
