Hello
An official 50ore SG O39 has a variant O39e with a missing line above the "S".
I found something similar in 10ore SG O33, Scott O17. I checked it with x30 magnification and the paper seemed intact. What could have caused it? Did anyone else run into such a variant?


In the next stamp, I found unfamiliar stamping on the back of the stamp. What can it be?


Thanks for reading.
