UV or not UV? That is the question

I have recently bought this note:

 

 

 

The catalogue says there are two types: one that has UV activity and one that doesn't.

 

I believe there is only one type and that the perceived “UV activity” is just reflection of the UV light from a particular ink colour.

 

Here's my note under 365nm:

 

 

It doesn't fluoresce, in my opinion. Parts of it are a different colour, that greenish colour, but those parts are also a certain colour under white light. It's a pale brown. I don't see it on the reverse and the reverse has no areas looking green under UV. 

 

I would like to know if someone has a note that doesn't look like the above under UV.

I believe, that generally speaking, it is ink areas which are printed to fluoresce under UV light are those which are considered to be UV security features on a banknote. I think you are correct in deciding that this banknote does not contain UV active security features.

 

Btw, what era, date, is the note?

It's a 1978 note according to all the info I can find.

I think that 1978 is on the early side for a banknote to include active UV security features, unless it is a high value note perhaps

Sometimes, UV activity on a banknote is incidental and not intentional.
