A half-penny not described in Sebastian Pawlikowski's reference catalog.
Variety with a striking engraver's error - illiterate writing of the word "Polski" on the reverse - PONLOEI (?) instead of POLONIE. In addition, the second L in the king's name composed of two unconnected vertical beams.
Despite the massiveness of the issue of this denomination, it is very rare to find half-pennies with errors. Usually, when they do occur, they are single rearranged or missing letters. We have such a striking mistake on sale for the first time.
Rarity.
A second, later type of half-penny with the letter n, dated 1407. From an issue attributed to the minter Nicholas Follisfessil, whose mark was to be the letter n (from Nicoulaus).
It is also characterized by a simplified iconography, which was supposedly due to the start of preparations for war with the Order.
