RR-, Silesia, Duchy of Legnicko-Brzesko-Wołowskie, Frederick II, Grosz 1543 date left, Brzeg, punch (ID) on DOMI

Coin from an old collection with a beautiful patina. A rare type of the 1543 Frederick II Brest penny with the date to the left of the eagle's head ( in this vintage it is the date that begins, not ends, the legend on the reverse). A different image of the prince - a smaller head with a pointed beard - more similar to those minted on Frederick's troikas, with a different image of the eagle.
Additionally, an unrecorded punctuation of the legend from IDOMI to correct DOMI.
Rare.
