Interesting piece with a different color of printing on the obverse, which we believe it took place at the printing stage.
The banknote itself does not bear traces of contact with water, hence we exclude any discoloration due to the chemicals used. The paper is not yellowed at the same time, hence it is not the result of long-term exposure to the sun.
One centrall bent. Two minor tears at the left edge.
Good, fresh eye appeal.
