1000 Yen, Low Serial Number

Nice find :)
Unfortunately it probably won't increase the value that much
The serial number has a double letter which means that it isn't one of the first half billion or so printed
There were billions of this note printed - yours has a brown serial number which makes it 2011-2019
Even perfectly uncirculated ones would not be worth more than double face and yours is more like F/EF (modern note grading is extremely strict any fold at all - and you can see one in your picture makes it EF or worse)
There could be up to around 18 million notes with serial numbers less than 1000 in circulation, so the serial number whilst cute probably doesn't add much value .
But nice find nevertheless.

Don't see the tear, but agree this is nothing really special.

They are issued in the billions !
