A very rare error.
On the reverse, in the word POLONIA, a misprinted letter N (in mirror image).
Occurring only on this one reverse stamp among all those used in Poznan for trojaks in the time of King Batory.
A variety with the mint mark of the mint manager, Teodor Busch, on the right side, and the date on the left of the Przegonia coat of arms.
First time in our offer.
