Peru 200 Soles UV Activity P#103

I am a bit puzzled by the UV activity of my banknotes.

If anybody has the 1973 issue of this banknote and can check the UV activity I would appreciate it.

This is P#103  N#267676

My 1973 banknote shows this strange pattern.

My 1974 banknote shows the number “200” at either end.

This kind of unusual pattern is often the result of a liquid (damage) that leaves behind an irregular pattern.  The UV activity is left from either the liquid or transfer from the surface on which it was dried.

That is what I suspected.

But I would still like to know if only the 1973 banknote is suppossed to have the UV “200” or if my 1973  banknote is fake.

The official publication from Peru's Central Bank does not mention banknote security features of any type, for any  banknotes; so I do not know which banknotes are suppossed to have UV security feature and which ones do not. I have other banknotrs of the same series were depending on the year, they have UV activity or they do not.
