Austria 1880 Newspaper Stamp Imperforate, Need Help To ID Variety?

Hello!

I need some help to ID this old Austrian imperforate newspaper stamp, nice "Graz" postmark. This should be Sc # P10 1880 Blue-Green but this seems to be an unidentified variety, can anyone make out the value on it?

Very hard to see, the paper is EXTREMELY thin almost like rice paper. The paper is 100% NOT like the other newspaper stamps I have from this series. The color is almost translucent...

There are no watermarks...just a small thin red line on the back.

Cheers and thanks again for all your help in advance forum! A wealth of knowledge here & appreciate you sharing it.

Opinion:

My guess is you have a Type ll
